Have you donated to the Mozilla Foundation so they can ditch financial ties with Google?

The anti-trust lawsuits with Google have Mozilla realizing they can't just be a company kept afloat by Google. Mozilla's priorities have been pretty complacent, basically just maintaining Firefox, sometimes Thunderbird, and a couple side services that have little financial incentives.

The current state of Mozilla is pretty odd since they rebranded to make it more apparent they're a non-profit, while also attempting to become more profitable pushing out new products and services.

Just for clarity, you do mean Thunderbird (the email client), not Thunderbolt (this new AI client)?

This is from MZLA Technologies, so is a sister product to Thunderbird rather than Firefox.

People "want" a lot of contradictory things. People "want" them to be less financially reliant on Google, while also "focusing" on a browser in a market that is entirely commoditized and subsidized by 3 of the 10 largest companies in the world - and having a wholly implementation independent browser engine when it's so massively difficult and capital intensive that even Microsoft gave up on it.

I agree with you, there are 1,000 different chat apps and just one Firefox. And the world needs Firefox more than it knows.

It looks like they might want to get into hosting/selling services to users on this.

From the FAQ:

> Is there going to be a hosted version if I don't want to deploy it myself? > Yes, we are planning to launch Thunderbolt for regular users but we do not have a release date yet.

This "Mozilla is distracted" narrative is a category 5 hurricane of unsubstantiated vibes from people who have no idea what they're talking about.

Some quick hits just from reading recent release announcements from December '25 through April 26:

- Hardware acceleration for faster performance with PDFs - Expanded WebGPU support - Faster page loading with compression dictionaries - Deeper hardware integration for faster video playback on AMD hardware - Better GPU stability and performance on MacOS - Faster local translation

And I'm only picking out bits and pieces. "Web platform" improvements are so abundant that reproducing them from any single release would be a massive wall of text, but for a few examples just from one recent release:

>Service worker support for WebGPU has been added, making it available in all worker contexts. Service workers allow WebGPU to run in the background, which is particularly useful for extensions and other pages that can meaningfully share resources across multiple tabs and time periods.

>Firefox now supports the Iterator.zip() and Iterator.zipKeyed() methods from the joint iteration proposal. This allows zipping together underlying iterators into an iterator over values grouped by position, similar to zip in many other languages.

>Firefox now supports the Trusted Types API, which is primarily aimed at preventing cross-site scripting attacks.

>Firefox now supports the Sanitizer API, which provides new methods for HTML manipulation. The element.setHTML() method enables developers to insert HTML content similarly to element.innerHTML, but without the security vulnerabilities such as cross-site scripting (XSS). A complementary method, document.parseHTML(), is also available for parsing HTML safely.

And on and on it goes with APIs, CSS and so on, and that's every release, and that's still not covering feature requests and cosmetic updates, or the constant security updates.

Guys, this is millions of lines of code and thousands of patches every quarter. While you were reading about AI features or poorly worded terms of service, they studied the blade..er.. they worked on real performance improvements. It should be a scandal that anyone in the comment section gets away with claiming they're not working on anything.

Firefox is pretty cool. Use it every day.

Blocks ads Multi account containers Dev tools very good

I never notice that it is in any way slow, except for those sites that need infinity cpu on any browser, like jira.

What specifically is the issue? To my mind it quietly just gets on with things.

> already painful and readily apparent, stagnation of your browser

What's wrong with Firefox? There are several things Firefox does that it's annoying to live without in other browsers (video pop-outs, competent ad blocking, etc). Is there some core feature that's missing? I'm subjected to Edge at work and I couldn't tell you a single thing it does that I'd want FF to do.

> and our standards bodies as entities distinct from corporations

Ok, I buy that.

Mozilla is doing exactly what you’re describing. They need revenue to ditch their direct financial ties to Google (and I wonder if they hire those high-salary executives solely in the hope of generating that revenue).

These AI products, along with all previous failed attempts, are just them trying to gain enough revenue to remove that dependency on Google.

Firefox has many weaknesses, but I never once thought “man, that thing is slow”. It isn’t, and chasing benchmark numbers is a waste of effort. A better security model or deeper customizability would be far more valuable.

And regarding (memory) performance, chromium has the "memory saver" settings for unloading tabs. I don't understand why mozilla thinks its acceptable to require users unload tabs manually. Who even does that?

Ladybird soon™

It's a crazy crowded space. Any entry into this field looks like a "me too" product driven by FOMO instead of being motivated by (a) serving customer needs, (b) serving social needs, or (c) making money. (All of which are fine with me) It will get 0.5% market share -- and I'm supposed to get excited?

If you lived in New York City you might think there are Duane Reades coast-to-coast but there are not. If you are based in the Bay Area you see billboards that are very different from anywhere else. I'd say the viewpoint is a lot like this famous artwork

https://en.wikipedia.org/wiki/View_of_the_World_from_9th_Ave...

but maybe instead of the rest of the US being 1/5 of the vertical space it is 1/25 of the vertical space. Problem is most customers do not live in the bay area and most web browser users do not live in the bay area and most web developers do not live in the bay area. Based in the Bay Area they can hop in their cars and drive the longest 40 miles in America to get to Google and Facebook's headquarters so Mozilla is talking to those people all the time and not talking to the rest of us.

We don't get costly signalling to show they care about the rest of us, we don't even get cheap talk.

They probably think René Girard is deep because they are surrounded by people who think René Girard is deep. If Mozilla wants to be relevant and not just an also-ran it needs to "think different" like the other 99.9% -- it's not that hard if you change your location.

Really the EU needs to apologize for those damned cookie popups and invest in a privacy-first browser. Whether that is "fully fund Firefox" or "fully a fund a Firefox fork" or pick up another browser engine or start a new one.

I see the warning lights flashing: a few years back web sites that didn't work with Firefox were few and far between, this weekend I bought tickets for a comic book convention and they took my money but didn't give me a ticket because the site didn't work with Firefox. I use Firefox as my daily driver so all the projects that I work on work with Firefox; the rest of my team doesn't give a damn and if you lose me another site will become Chrome-only.

These two goals:

> ... please stop working on projects distracting from the complex and necessary work of browser and web standards stewardship.

> Ditching any direct financial ties to Google or any other browser vendor is both important and necessary...

are inherently contradictory. If you do not want Mozilla to have revenue from search vendors that also have browsers, it has to come from somewhere else. Or are you suggesting they switch the default search engine back to Yahoo [0]?

I am not trying to defend the projects they have chosen to work on, but you have to understand that reducing dependence on Google is exactly why they are working on them [1].

[0] Even when they did that, it was for the US only, and Google was still the default for most of the world.

[1] Although in this case, this appears to come from the Thunderbird organization, so unrelated to the browser. Money is fungible, though.

I remember that Firefox is orders of magnitude more performant in css processing, especially for complex documents with many elements. Can't comment on the javascipt interpeter, so I assume firefox is losing points somewhere else outside the screen painting engine.

I want them to actively seek foreign sovereign tech funding which come with stipulations that commit Mozilla to certain levels of privacy and anonymity.

I want them to go cap-in-hand to other countries and say "if you don't fund us then you are letting the US and surveillance capitalism get between your citizens and their government" and "do you really know what Chrome is doing with your data?"

I don't want to pretend they are simply part of a browser marketplace, but rather have them realize they are part of a civil rights effort, with powerful non-market forces they can ally with.

And I want those governments to commit to progressive enhancement guidelines like https://www.gov.uk/service-manual/technology/using-progressi... so new alternatives like Ladybird can start, and further require their agencies to test on a Firefox branch with no AI, no location tracking, full ad-blocking, etc. because while the market is free to ignore certain non-profitable users, a government should not be allowed to ignore some of its citizens.

I don't see a contradiction there.

Why is this related to Firefox?

There is "only one Firefox" but Firefox exists in a market that is not just commoditized, but subsidized to the tune of billions by 3 of the 10 largest companies in the world.

The world may need Firefox but it's funny how people complain about Mozilla's dependence on Google while also complaining about every attempt to become more financially independent from Google.

Maybe you wouldn't be so tired if you didn't make assumptions of things to be mad about

What fatigues you about this observation?

Would recommend exercise

RIP Firefox OS

It doesn't support WebNFC or WebUSB.

Yes there are things that Firefox does better than others, and that is one reason I use Firefox. But there are definitely things I would like to see improved, like:

- PWA support on Linux

- better performance

- devtools should be able to handle sites with large amounts of js with sourcemaps

- fix a number of bugs that have been open for a long time

- don't lag behind standards as much (I'm not talking about things where they intentionally don't implement problematic "standards" pushed by google)

- make it feasible to embed gecko in other projects similar to how chromium is used by electron and webkit is used in "webviews"

Some folks have already discussed this in sister comments to the one you're responding to, but it's a common enough hn discussion topic that searching will answer beyond that (better than I can regurgitate here.)

And you your point, AI is probably eating search and with it the prospect of search licensing revenue. Not sure yet what paradigms will be most important to the browser experience but it's critical to get in early and make the inevitable early mistakes and work through them.

that is in beta

Some of us are out here still waiting for Firefox relay “premium” to launch and provide disposable mobile numbers like they do email addresses.. but product has for some reason been stuck on “join waiting list” for what feels like an absolute age.

Could those external APIs point to locally hosted models?

"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."

"Please don't fulminate."

"Don't be curmudgeonly. Thoughtful criticism is fine, but please don't be rigidly or generically negative."

https://news.ycombinator.com/newsguidelines.html

On the bright side - it doesn't load without javascript ...in Firefox...

>120k LoC of probably largely vibecoded nonsense for a window with a text box and a button that lets you send and receive some data over a HTTP API.

"I will make loads of assumptions without checking so that I can invent reasons to get mad"

Note that about 30,000 of those lines are JSON files for localization and testing, as one example.

Wait what ? Did you include libraries imported by NPM in this count ?

Hi, I'm on team that worked on this. No it's not vibe coded. We do pretty intense code review of every PR. It looks like the number you're seeing is including lock files and artifacts that are not part of the core coverage.

It is very cool! I'd go as far to say it's a great browser in fact. I simply want it to exist and be such in perpetuity and lead by example like it has in the past. I see it as a follower instead of a leader these days, largely to Google, but also Safari and to some degree Edge (by simply stealing the blink renderer)

The Mozilla org continues to produce a very capable browser, but it's now 3rd or fourth fiddle on a stage their misteps helped orchestrate in their demotion.

Edit: clarification

I use it daily, but Chromes dev tools are better. I always wind up back in Chrome to debug things.

Here are a couple:

1. The inability to set a specific page for new tabs to open on. That is ridiculous.

2. The mobile version sucks, specifically because bookmarks are buried under an absurd number of menu levels. And they're also broken up (without user approval or any way to stop it) into "mobile" and "desktop" bookmarks. WHY? The entire point of syncing is to have them all the same.

I want to like Firefox. I went back to Firefox for the first time in decades last year and gave it up after a couple months because #2 was that annoying. So brain-dead.

Oh yeah, and another one was that "never remember history" does, in fact, remember history. What Firefox really does is "stop adding to history." And the bug report on it resulted in several YEARS of debate over how to "fix" it. The latest I saw is that they're actually NOT going to fix it, but rather add more text (somewhere) to say basically, "This doesn't do what you think it's going to do."

If fixing a defect like that requires years of committee back-and-forth, the product is finished.

Web usb and serial are not just missing, last I checked Mozilla is opting to not implement based on their moral stance. It just puts them behind for some stuff.

In contrast, the Multi-Account Containers system is the primary reason I avoid Firefox.

While it is meant to be an alternative to Chrome's profile switching, it is more a workaround than a complete replacement. I need entirely different sets of extensions for personal, work, and school environments, something containers can't do.

Firefox's actual profile support is beyond terrible. To launch a separate instance, Firefox requires many more clicks than Chrome, all within a Windows-2000-style UI. Not to mention that there are weird glitches in their implementation.

Firefox is not usable for me until they actually spend time improving their multiple profile support.

It's slow. It almost always trails Safari and Chrome on most benchmarks.

See e.g.

https://www.reddit.com/r/firefox/comments/1ljns9o/freshly_re...

Firefox on iOS still doesn't support extensions or adblocking - something Safari (and other browsers as well) do.

reddit tab, firefox: 428mb. same tab, chrome: 78mb.

I'm building a fairly complicated browser extension [0].

Debugging the extension on Chrome, it works great. On Firefox, it is nearly impossible. There are a litany of compatibility issues that make it "different" than Chrome, despite the extension being very much standards based. It is really frustrating and makes me dread getting bug reports.

To be fair, Safari is even worse and I haven't even touched Edge yet.

As much as I'd love to have options in the marketplace, standards based compatibility between offerings should be a top line requirement.

[0] https://oj-hn.com

I use the about:memory tab whenever I need to clear some memory. However, it can't unload tabs.

We're not, but companies are not courageous enough to explore new names.

I've already used up "cum" btw, so you're not allowed to name your product that.

Where exactly do you expect Mozilla to gain revenue from other than non browser projects?

Do you want people to pay to use Firefox?

They (like many) are afraid to become svn as the world is apparently taken over by git. Well-maintained but irrelevant.

Well, see, one is Thunderbolt io, and the other is Thunderbolt.io.

I agree that Mozilla is a breath of fresh air, and I am happy to see this extending to AI.

> Businesses definitely want to control the AI they're using (especially with RAGs of their own data) instead of just throwing it at their LLM vendor and hoping for the best

Yes, agreed on that. I'm not sure I'm clear how this really helps that; I suppose it's a frontend that they don't have, but there are a bunch of those already.

It doesn't seem to help them control the _actual_ AI, i.e. the model, which still has to come from somewhere.

It goes to show that Mozilla(s) could, if they really wanted, restructure Mozilla Corporation / Foundation.

(edit - to allow users to fund Firefox, allowing us to better sleep at night, and to align our incentives)

> This is from the separate independent team that works on Thunderbird, not Firefox, so there isn't any resource contention happening there

I would rather have them work on Thunderbird.

Can the team please use that money on making thunderbird look like the nice UI mockups that were published that don't look anything like thunderbird.

...and also differs in just three characters from another Mozilla product.

"I'm using Mozilla Thunderbolt."

"Huh, do you mean Thunderbird?"

"No, Thunderbolt!"

I see no reason this product should exist even under the Thunderbird umbrella, especially if ANY resources under ANY Mozilla org were employed in this. This product is a distraction from their core mission in either case.

Updated!

> Really the EU needs to apologize for those damned cookie popups and invest in a privacy-first browser.

I love them. They are not mandatory, only shady websites that rather sell users information than providing a barely functional homepage. Yes the popups suck, but I'm very happy that this exposes the behavior and priorities of the industry.

>And then of course it's also the same as a well-known hardware interface.

The cherry on top is that the domain is thunderbolt.IO. No other TLDs to pick from?

  > Imagine that there is such a thing as a person in charge of choosing technologies for organizations, and that you're such a person. That's who this is for.

The "Announcing Thunderbolt" page actually makes this clear, the submitted URL does not. Maybe the submission should be changed to this URL instead:

https://www.thunderbolt.io/announcing-thunderbolt

Yeah it seems similar to Gemini Enterprise. There you can deploy "apps" (basically front-ends) on top of the LLM that come pre-configured with plugins to access Google sheets, Databases, your Jira boards, etc.

So all this is doing is adding context for the LLM and some persistence.

I have yet to see a compelling use case for Gemini Enterprise at my company but we're still experimenting with it.

Having the best browser should be Mozilla's first priority.

Investing on AI is not going to make them less financially reliant on Google.

They could start getting some of that goodwill back by not paying their CEO a multi-million dollar salary and opening donations to actually help fund Firefox.

The fact it's that for a normal usage, Firefox with uBlock Origin it's faster that Chrome without ad blocking. On Android this is especially noticeable.

Why is this related to Firefox?

I'm perfectly fine with Mozilla working on other things as long as those things are profitable or at least self-funded. As long as they are not leeching donated resources from Firefox or Thunderbird, I don't see a problem. However, I wish I had some kind of assurance that the money I donate to Mozilla would go to Firefox and not some other project like this.

Thunderbird was literally asking for donations just a few days ago?

>Thunderbird is revenue positive

Hmm, I thought the for-profit Thunderbird pro hadn't launched yet?

I know Thunderbird is for profit, but what are they profitting from without the paid service, and how much of that profit is going into this unrelated Thunderbolt AI platform, exactly?

Are they allowed to reuse Thunderbolt when it's already taken in the same industry?

> What does this one differently that the other thirteen in a dozen don't?

Mozilla's a lot more trustworthy with privacy and data, and they're unlikely to sell the project to someone who only wants to stuff it full of malware/adware/crypto stuff - or do it themselves.

> What's wrong with Firefox?

It seems like every thread talking about Firefox always has someone asking that question, so if you search back you should find plenty of reasons. Unfortunately, it’s been my observation that valid and polite criticisms always get downvoted. I don’t understand why. It’s not like downvotes are going to make the problems disappear.

Most of us would like Firefox to succeed, and it’s none of our faults that Mozilla is constantly neglecting it and going off on wild goose projects which get promptly abandoned.

I mean there's already an established theme... how hard can it be?

Fire-fox

Thunder-bird

River-wolf

Stone-raven

....

I'd argue these are not _contradictory_, just incentivized financially to continue since that's how they've operated. What i'm suggesting is a change. There's plenty of counter examples where diverse funding models for community projects can work without taking vast sums from a single, direct competitor. Linux is one. Imagine if MSFT was the sole contributor to Linux and how that would have shaped its development. In recent years MSFT may infact directly contribute developers and funding to linux, but they have a vested interest in doing so, as they run more Linux VMs in Azure than Windows VMs these days...

Thunderbird (the email client) was spun off from Mozilla Corporation into a new for-profit company called MZLA Technologies. Both corps are still subsidiaries of the Mozilla Foundation. Thunderbolt is a new product from the MZLA Technologies team.

Because Mozilla is wasting money on something other than their core product, once again.

I had to check the comments here to even see what this product was for that reason.

How much UI text does this thing have that it needs thousands of lines of localization? Where are these files?

Especially curious because I see a whole lot of hardcoded english text in there…

That's still an immense amount of code for a chat interface essentially consisting of a text box and a button, which any OS (mobile or desktop) can usually throw up in a few lines of code.

22,056 is not about 30,000. Per scc:

  Language      Files     Lines   Blanks  Comments     Code
  ─────────────────────────────────────────────────────────
  TypeScript      760    109110    14500      7397    87213
  JSON             41     22056        6         0    22050
  Markdown         56      7150     2086         0     5064
  YAML             33      3965      406       208     3351
  ... and many more with fewer than 1k lines

Regarding "loads of assumptions," it's hard to tell how much of this is vibecoded slop (definitely non-zero looking at the commit log), but I don't think it's that outrageous to claim 87k sloc is too much for a textbox and an API wrapper.

Not nearly soon enough. But yes, there is hope. Far away hope, but still.

My comments teaches the reader that the codebase of yet another identical LLM chat app by an organization most well known for wasting money on stupid shit is one hundred and twenty thousand lines of fucking code. If I can't post about that without getting admonished by a snarky moderator and his copy/paste skills then go to hell, I don't want to be here and evidently anyone who is not interested in circle jerking around the utter shitscape that is the current state of the software industry shouldn't be either.

Please consider this an official request to delete my account and all the data in it, I'm done with this.

Are you arguing that 90k LoC for a window with a text box and an overengineered textarea tag is somehow more acceptable than 120k?

There are plenty ways to fund digital commons, including people volunteering their time.

I wonder how much slower Firefox would have to be to invalidate the mental health gain not imagining every single keystroke going directly to Sundar.

it is a patreon style thing, they are donation funded. I think the poster is saying that they arent being frivolous with their money like some people have a bad taste about firefox

I worked in Mozilla previously for like 5-6 years. I think the supporter of Mozilla is a lot more trustworthy with privacy and data, but not Mozilla itself... I think they claiming that they do this and do that, but actually speak louder than action. My personal takes from the upper management is also not that good.

If you were not working with Mozilla Asian area, you know far too less. They had a browser in China that redirect to different website for profit before every connection and some affiliation. By doing so, is it privacy or not? Oh, look at Mozilla Japan volunteers, they shut everything up because things went wrong.

Hmyeah but many others like openwebui are self-hosted and open-source so it's not really like they are untrustworthy.

Yeah. Mozilla openly state that they DO sell your data.

How much of that privacy matters when you're connecting it to third-party agents/models?

Because Windows doesn't go open-source and others can't build their OS from windows like chromium. With OS, there are no open source kernels that are actively maintained and security-fix bump every month by full time staff of giant corporation. With browsers, devs already have an open source engine with most of the work and build are from full-time staff of a giant corporation, and then they just lazily build "their own" browsers upon that and brag on social media.

Build your own browser engine and see how you can pay the devs to make them work on it.

Oh that's really good. You're right, something like Riverwolf would fit their branding much more consistently. Just as long as it's not Bikepelican, I'll be happy...

  > spun off from Mozilla Corporation into a new for-profit company called MZLA Technologies. Both corps are still subsidiaries of the Mozilla Foundation

I am a happy Thunderbird user. But when I see such reorganizing and deliberately confusing naming, I assume that there is somewhere intent to deceive.

TIL, thank you.

I imagine that would bump that number to milions.

I just checked one old take home task in Angular I did last year and the total number of lines is over five million over 35k+ files.

I don’t think so. I just used a public GitHub LoC counting tool directly on the repo, there are a few.

https://ghloc.vercel.app/thunderbird/thunderbolt?branch=main claims 141k and most of it is Typescript.

Funny, I have it exactly the other way around!

One difference I've seen with FF vs Chrome is when finding the events to bind to each element. In FF, the event tag on the element is clickable and gives you the name and the line number in the JS file. It makes finding the code very easy. I have not seen that in Chrome. I rarely use Chrome, so this one thing leads me to saying FF's DevTools are better, at least for me and how I use them.

I definitely have not had that experience, although use FF for personal, various work, and various educational places.

None of those have required me to install a particular extension..

Of course thats not to deny your experience!

The only time profiles ever come into it, for me, is using web driver, playwright, or whatever.

I guess maybe the usage stats dont support making the profile selector better.

But also, maybe its a thing they would accept a change for?

WebSerial just landed in Firefox nightly! https://bsky.app/profile/paulusschoutsen.nl/post/3mjfdx3ujta...

Myself the profile support is the absolute worst thing about Chrome. I just want to log into some web site, I don't want to fight with the profiles to get things done.

For those few applications where I really would need profiles I will just open a different browser, so I still keep Edge/Chrome/Opera around for that rare situation. I don't need something that complicates my life every single click but it is the whole ideology of the Google Economy that they want you to spend 1% of attention on things that matter to you and 99% on things that don't.

Okay, I'll give you that. Granted, I've used webUSB exactly twice, once with a Flipper zero and once with a mechanical keyboard. If that's the worst of it, the parent comment calling it "painful and immediately apparent" seems a bit dramatic to me.

This is not meant to be an alternative for Chrome's profile switching. It's a different use case entirely.

As you yourself mention, Firefox has actual profile support, which may not be as good as Chrome's, but at least compare like for like.

Firefox has a new Chrome-like profiles support as of v149.

https://support.mozilla.org/en-US/kb/profile-management

LMFAO. Containers are not for profiles-purpose. Everyone who needs profiles know this.

And Firefox now needs 2 click to switch profiles.

I don't care about benchmarks.

Because Firefox is the only thing that lends Mozilla any credibility.

Thunderbolt was funded from a grant, not donations.

https://github.com/thunderbird/thunderbolt/blob/main/docs/fa...

And?

This was built with money from an grant from Mozilla. See the bottom of this page: https://www.thunderbolt.io/announcing-thunderbolt

Thunderbird currently runs entirely on donations, even though they have paid products in the pipeline.

I think a piece of software running on donations is not running off "charity". It's just a business model to not charge every user. Similar to how Twitch streamers operate, or my local theater group.

You can read how they spent money in 2024 [1].

[1] https://blog.thunderbird.net/2025/10/state-of-the-bird-2024-...

They have enough money for a legal dept. so I imagine so. But it's a confusing choice IMO. Not just because thunderbolt but also because thunderbird as someone else pointed out. But maybe they are trying to make thunder their 'thing', like apple puts an 'i' in front of everything?

Coming soon the browser rebrand to Thunderfox! :)

I'm somewhat a fan of Mozilla, but their weak governance with regards to actual plans for the future, a couple of questionable partnerships, and the graveyard of products makes it hard to trust based on a 15+ year-old reputation. Would love to see where Mozilla has meaningfully contributed to the modern tech space (things we all actually use, not Mozilla versions of more popular apps/tools)

This Mozilla?[1] The company whose 85% of revenue depends on an adtech giant?

They're certainly doing better than others in this space, but their track record does not inspire confidence for anyone concerned about their privacy and data.

[1]: https://en.wikipedia.org/wiki/Mozilla#Controversies

I use Firefox on both Linux and Android for 99% of my web browsing needs. At least for me it's the best browser out there, and doesn't seem neglegted at all.

Upvotes are not going to make problems actually relevant to solve.

The question keeps getting asked because people say they have problems. Answers (if any come) tells everyone what the problem is for this one user that raised it.

In aggregate we can all see that the problems are not very real for the vast majority of users.

The biggest problem users actually face with using Firefox is that web devs don’t want to support more than one browser and they have picked Chrome now. Or IT departments have blessed one and only one browser on corporate machines and it is the one most corpoware developers build extensions for.

Chasing web standards is a second order problem and will not make the user experience better in a relevant manner for end users. If web developers want an open web, they have to work to support open browsers.

Yeah the criticism is not invalid, but it is also often half-relevant soapboxing and I would wager that is why it tends to get downvoted.

Thunderbird is under MZLA Technologies Corporation, their money and resources are unrelated to Mozilla Corporation, who pays money for their Firefox.

Fair enough if it’s not vibe coded, I’ll take your word for it. Code review seems like it’s mostly bots (Claude, Cursor, Greptile) from the PRs I looked at?

Nevertheless, AI use is not what really stood out to me. It’s that it’s SO MUCH CODE. I have no idea how you guys maintain or reason about the quality or security of something like this. Good luck, I guess.

> The inability to set a specific page for new tabs to open on. That is ridiculous.

I've been using the "New Tab Override" extension for almost a decade at this point. Sure, it would probably make sense to have as a baseline feature, but I installed it so long ago and it's continued working the whole time that it's not really something I think about anymore.

It is so frustrating how every thread about Mozilla has people getting upset about contradictory things.

Half the thread impunes Mozilla for taking so much money from Google and imply that they are controlled opposition, and the other half gets upset when Mozilla doesn't implement every standard that Google tries to steamroll through the standards bodies because of objections to how they can be used for fingerprinting, or complains that the attempts at anti-fingerprinting break websites, etc.

Sometimes it's not even different people, it's the same people punching them for contradictory reasons.

Mozilla is not perfect but they get all the downsides of being methodical and privacy focused alongside none of the benefits. Everybody hates the "side projects" unless it's Rust, Servo, LetsEncrypt, Thunderbird, contributions to Opus/AVI, etc. and you can be sure they'll be criticized if they "focus" by touching investment in any of those by the same people.

What are the other competing browsers? There's chrome(and the derivatives), safari, firefox? safari exists only because of ios lockin. Aren't most other browsers an increasingly smaller share? Genuine question.

> It just puts them behind for some stuff.

Yeah, it really undermines their ability to compromise user security and privacy.

How many milliseconds do you think this page took to render? I usually click and it's already done.

I will eat the RAM penalty to resist the Chromium hegemon. Grateful to have any alternative!

This is not airport. No need to announce. Good bye and go to the place that you tell others to go too.

I don't think volunteering is going to cut it. Big orgs have big money and public commons are just targets to be controlled exploited.

mozilla employs 750 people and has a 1/2Bn dollar deal with Google and still their browser is absolute hot garbage. i think volunteering won't cut it.

Firefox on iOS isn't really a Firefox because Apple doesn't allow alternative browsers. It's a Safari skin.

I get 80mb for reddit on firefox.

That number can be down to any number of different factors on reddit itself. Having an autoplay video running, etc.

The standards used to be there. Chrome decided they made ad blocking too easy and unilaterally changed the standard. Firefox is still on the standard. Chrome is what deviated, and while performance was improved, that was definitely not the motive.

A leading web browser can not be built and maintained by volunteers.

No. Thunderbird has its own merits and they work without Firefox. Mozilla has credibilities in e-mail because of Thunderbird. This topic has 0 relations to Firefox.

I think the rest of that line is really kind of important:

> Thunderbolt is funded through a grant from Mozilla.

Is there any way that that's not taking dollars out of the same organization that's funding Firefox or thunderbird?

Mozilla gave Mozilla a grant, so that's all there is to it I suppose.

Thanks, that's helpful. This says about ~70% of the money was paid to employees, ~10% infra costs, the other ~20% various other fees and smaller expenses.

It would be interesting to have a breakdown of what part of the Thunderbird team is working on Thunderbird, Thunderbolt, or other forms of thunder.

Took me a bit to find, so here's it quoted:

> Thunderbolt is funded through a dedicated investment from Mozilla and is being developed by a separate team focused on enterprise AI products, distinct from Thunderbird’s donation-supported consumer product work.

Very happy to update to Thunderfox.

Good for you. I’m genuinely glad, you should use whatever you like, I don’t care for flame-wars. For me, it lacks several must-haves (I’m not going to waste my time repeating them, history has shown that’s a stupid waste of time and the downvotes on the original comment only prove my point). That’s why we have so many apps, everyone has different needs.

that is the firefox groupn not thunderbird. Diff bro

LMFAO. You web devs just want more tools to fingerprint and track users. When Firefox raises privacy concerns for your spyware tools, you play like victims and say that "Firefox doesn't want better for users". F that.

Ah yeah, after accusing others that they vibe-code without proofs, no apology and steering the accusations to other things?

New Tab Homepage is another alternative

Essentially all of Firefox' incompatibilities with a website reduce to Firefox not allowing the users to be tracked or fingerprinted by default. Webapps that rely on fingerprinting as a replacement for device tokens will likely not work. Because fingerprinting is bad and I don't want it to work. The people your bank pays to implement that are the same companies used for cross site tracking. It only works because tracking works. ReCaptcha can break for similar reasons, but there are better options for captcha and the need for captcha itself is possible to eliminate with various strategies depending on what it is being used to mitigate.

> Half the thread impunes Mozilla for taking so much money from Google and imply that they are controlled opposition, and the other half gets upset when Mozilla doesn't implement every standard that Google tries to steamroll through the standards bodies because of objections to how they can be used for fingerprinting, or complains that the attempts at anti-fingerprinting break websites, etc.

Yeah, double standards at its max. Firefox inputs every privacy concerns for these APIs that Google puts 0 Vietnam Dong to care about users' privacy. And those people cry about why Firefox doesn't implement it.

HN is not the most complex website rendering wise by any imaginable metric. I presume HN renders equally as fast on lynx or Mosaic from 1994...

And they're taking money donated towards Thunderbird development and spending it on random unrelated AI slop ideas that nobody asked for. You really don't see anything wrong with that?

Surely you can agree that when you open Thunderbird and are met with requests for donations, if you chose to donate, you'd expect that money to be invested in Thunderbird development, and not 10M Claude tokens to vibe code Mozilla's latest groundbreaking AI B2B SaaS idea?

But despite that, Mozilla is still far more trustworthy than virtually everybody else. Who would you trust more? I imagine it's a very short list. Which is a sad state of affairs.

No, this was built with money from an grant from Mozilla.

Wait what, they took donations to pay a team to build a mail client and had them build an AI thing instead? Or have I got that wrong.

I’m not sure if it’s fair to describe a "wholly owned subsidiary" as unrelated.

> Thunderbolt is funded through a dedicated investment from Mozilla and is being developed by a separate team focused on enterprise AI products, distinct from Thunderbird’s donation-supported consumer product work.

Emphasis mine.

It's a problem. I use Firefox as my daily driver -- it used to be I ran into incompatible sites once a month or less except for YouTube which intermittently punishes users for browsing with Firefox. Now I have a serious problem every week like an online vendor or bank or something that doesn't work with Firefox.

Firefox is a little slow for an internal application we have that loads 40,000 rows of data into a grid but otherwise all our stuff works with it because I develop Firefox first and I think a few of us are all that really stands between Firefox and oblivion and probably are doing more work than a lot of the people they have on the payroll.

There's a lot of good use-cases of Web usb, you can't just cut everything which might have privacy aspects otherwise the browsers wouldn't have canvas or even gpu rendering.

HN is a fast site (comparatively; most websites are unnecessarily slow). It’s a bad measurement.

Nope.

https://github.com/OrangeJuiceExtension/OrangeJuice/blob/5be...

Firefox often groups tabs from the same site into one process. With large numbers of the same tabs open in both, check the total memory for all firefox processes and all firefox processes. You will likely find firefox actually uses less memory than chrome.

The endless excuses and lies.

It was the same page, both on old.

Orion on iOS is also a Safari skin and supports extensions

Right. Firefox stands alone as the most successful self financed full stack browser that's ever been made without being subsidized by outside revenue streams. I like to use the example of Opera. If "make a better browser" won market share and business creativity won stable revenue, we'd all be using Opera right now because (sorry Mozilla), no browser company was ever better than Opera in my opinion.

In 2026 the rules to making a good browser are (1) already be a trillion dollar company, (2) use Chromium, (3) have some form of distribution lock-in over billions of devices. Otherwise you're cooked. Mozilla swims against the stream better than anyone.

I don’t know, but there are other ways of funding besides -completely- volunteer run.

Take look at Ladybird

https://en.wikipedia.org/wiki/Ladybird_(web_browser)?wprov=s...

The EU says it cares about privacy. although it's actions have normalized enshittification; the EU could fully fund Firefox or a Firefox fork or another browser in a second and stop all the trackers right in their tracks.

Why do you know that nobody asks for? Are you in the team?

Stop spreading misinformation, it's funded by grant money https://github.com/thunderbird/thunderbolt/blob/main/docs/fa...

No, this was built with money from an grant from Mozilla.

I don’t know why you’re downvoting, it’s a fair question based on the above comments.

>Who would you trust more?

Nobody I'd mention on Hacker News!

No what? That doesn't contradict their comment about Thunderbird.

There's a reason that https://addons.mozilla.org/en-US/firefox/addon/canvasblocker... exists, though; a reasonable person could argue that firefox should be restricting canvas/gpu more than it does.

Yes, it's unrelated. Each one has its own resources and roadmaps. They are totally not dependent on each other. Thunderbird and its roadmaps/projects are not affected by Firefox' earnings at all. One's development doesn't affect the others.

(I work on Firefox Web Compatibility)

If you have specific sites that aren't working, please let us know and we can investigate and try to fix them.

The usual reporting channels are using https://webcompat.com or the "Report Broken Site" tool in the Firefox menu. Of course I"m also happy to take bug reports here if you (or anyone else) have them.

HN is a good website. Ebay is another good example where JavaScript is optional but with good functionality. Marko was mocked, but now Astro is cool because they invented ssr...

What are those use cases? It seems like a giant hole punched all the way from a tab's sandbox through the process boundary and out to the kernel... Yes, gpu rendering is a great example of the same problem. Canvas at least has some intervening layers depending on implementation.

And Brave on iOS has blocking built in to the browser itself instead of like Firefox on Android where you have to trust a 3rd party dev.

It's American company... unlikely.

Ah yes, a grant from Mozilla, to Mozilla.

I think "No, this was not funded by donations".

pianu.com used to be a website where you could learn piano by connecting your piano through usb with the browser. It seems defunct now but I found a video demonstrating it : https://www.youtube.com/watch?v=kTBmRV02NgI

I used something similar in the past. It was a legitimate use case for web usb which changed my mind on it quite a bit.

https://www.charachorder.com/ sells ergo keyboards and allows you to update their firmware directly in the website, through web usb. No local apps at all. Also an improvement in overall security from having to download some .exe / .dmg and running it locally.

GrapheneOS for example can install with web usb, I think it makes it much easier for people who aren't too tech savvy to switch.

Somebody also recently shared an awesome project which let's you use an usb printer regardless of your OS driver.

To be quite clear, I trust gorhill more than I trust mozilla.

Almost all of the gui software for programming keyboards with QMK uses webusb or webhid, so you either have to use a chromium based browser or an electron app that is basically just a wrapper for chromium.

LMFAO. Brave uses uBO's lists and filters, including trusted filters which have much more capabilities with much more risks to your sites' data and they allow that on all other lists too (even uBO only allows their own lists as trusted by default, other lists need to have permissions from users manually). That's how they can block youtube ads, and no they don't code their own filters for youtube ads either. And be assure that they can't check 100% all commits from uBO and other lists either.

If you want to play "no trust to a 3rd party dev", you should not use Brave's adblocker either. Or at least turn off all the lists inside it, and use your own lists. Your security risk is in those stock lists.

Then fork it.

Besides, the one thing Mozilla could do to be relevant to 99.9% of web users is to move somewhere other San Francisco and turn their office their into a homeless shelter. They should go to Dublin or Frankfurt or Barcelona, anywhere.

Yeah, it's a shame Qt/C++ doesn't have any way of interacting with USB devices and there's no libraries for that, otherwise there could be a native GUI app for QMK. Or failing that, because Qt is simply too difficult for programmers to figure out, maybe some day there will be a way to deal with USB devices from Java, then at least we could have an AWT app (or I guess Swing is the new hotness now?).
