Tor browser removing various Firefox AI features

MrAlex94

Just an FYI for anyone who is interested, I’ve also been doing the same for Waterfox.

Mozilla have taken into consideration doing things locally, such as tab organisation and the likes (one would assume pre-GPT era and with regard to features not utilising LLMs this would’ve been branded as ML functionality) but I’m not fully convinced this still won’t open up potential security issues in the future[for users of AI browsers].

For Tor users this seems even more of an issue as one would expect nation-state actors targeting undesirables would look for any potential weak spot to exploit.

Separately I suppose this brings into light how utterly crazy it seems having AI features in the browser chrome versus limited to the website content process/sandbox. It seems like a privacy and security nightmare and now everyone and their gran are releasing “AI browsers”, even the Firefox-based ones inspired by browsers such as Arc and Dia which seem like absolute privacy nightmares.

Seems like slick branding and marketing gets you a pass today when in the past such egregiousness would receive a load of flack cough Avast “secure” browser cough

Either way good job to the Tor team, I sympathise with how much extra load this adds to each rebase.

alimbada

What else does Waterfox remove? Does it still support signining in with a Mozilla account to enable sync features? Would be nice to see a comprehensive list somewhere; I couldn't see anything on the Waterfox homepage or the GitHub README.

MrAlex94

You can see here[1], I'll avoid pasting again. But yes, can still use a Mozilla account and the website is getting a refurb - I will add a third hard thing in computer science.. letting people know all the things you've actually built :')

Thanks for maintaining Waterfox. For me it has been working without issues, basically Firefox but with reasonable defaults, and I don’t have to constantly look for and manually disable “features” like these.

Noaidi

Thank you! Downloading Waterfox now and spreading the word! This AI jamming its way into everything needs to end.

Didn’t know Firefox had an “AI sidebar”

https://support.mozilla.org/en-US/kb/ai-chatbot

Seems to be unconnected to any model and off by default.

tyre

I’ve found it super nice.

Similar to the “AI should be an assistant programmer, not an independent dev”, having Claude there and being able to ask questions about specific topics while I read is fantastic. Especially for scientific papers that are outside my specialty (i.e. all of them.)

koakuma-chan

I have a Gemini sidebar, it just appeared out of nowhere one day, but I find it useful though. You can give it a URL and it can summarize it or whatever.

thrance

Didn't know about it either, until it got pushed in my face a few days ago, for whatever reason. Didn't leave a great taste in my mouth.

janwl

I’m used to all browsers adding features that I don’t want every few months. I just disable them and forget about them.

bokchoi

It was weird when it just showed up one day, but after using it a bit, I like it.

wartywhoa23

Regardless of what they do on the user's end, their rear end became too ugly for a tool which ostensibly provides anonymity, because it will end up on a 185.220.0.0/16 exit node way too often for any tales of decentralization to hold true.

Seattle3503

It makes me a little sad we only ever see FF hit the front page of HN for stuff people are angry about. The FF team building useful features like tab groups that are improving UX. But I guess if it bleeds it leads.

noir_lord

They make such strange choices though.

Like `Firefox Data Collection and Use` which includes `Send technical and interaction data to Mozilla` and some other stuff is on by default. [1]

Glean data is here [2]

Historically I don't think FF would have made that decision - now I have to periodically check what else they turned on without me asking.

I generally don't like telemetry but I really don't like telemetry that is on by default - that very much should always be a "Would you like to?" question.

janwl

Maybe the Firefox team should stop doing bad things if they don’t want people saying bad things about them.

lxgr

One person's bad thing is another person's much-anticipated feature. As long as they're optional and useful for enough users to justify the resource expenditure, I really don't see the problem.

noir_lord

Optional and off by default.

Telemetry is on by default in FF.

YetAnotherNick

Not getting in front page is likely not better then getting on front page due to controversial thing.(AI isn't "bad", its controversial)

The point is that it's the least bad browser ecosystem and it only gets negativity whereas Chrome, Brave, etc. get mostly dickriding instead.

nerdponx

I gave up on Firefox, sadly. I still use Thunderbird (which is apparently no longer part of Mozilla), but I couldn't deal with FF and Mozilla screwing around anymore.

I switched to Orion which has been working great for me. I'm happy to pay money for my browser and be confident that the money is actually being put towards maintaining and improving the browser.

I want Firefox to succeed, I just... can't justify it.

I wonder if they'd do better by charging $10 for a compiled binary and distributing it on Linux as an AppImage. I'd be happier to pay for that than send an unrestricted donation to the Mozilla foundation. Normally I frown on unrestricted donations, but something seems really off over there.

Mathnerd314

There was a whole experiment with this "Tab Candy" thing a few years ago. And it failed and Mozilla disabled it and it got silently removed, well, almost, because a fair amount of people complained. I wouldn't be surprised if today's tab groups go the same way. Browser innovation is hard and at this point most of the innovation is in forks of Firefox, rather than Firefox itself.

kmacdough

Tab groups have become incredibly popular and were subsequently copied to Chrome.

akimbostrawman

>building useful features like tab groups

wow what an achievement. Vivaldi which has 1% of there budget had that feature for almost 10 years. Despite almost half a billion dollar budget almost all there good UI changes come years late being the last to add them for example profile management.

It is honestly embarrassing to compare Mozilla to companies like brave that actually created a private ecosystem without subsidization from there competitors.

swills

Am I the only one who remembers the old tab groups that were removed before these new tab groups were added?

Edit: Ah, it seems Mozilla remembers: https://web.archive.org/web/20151112023150/https://support.m... (linking archive.org in case they take it down, this is the first copy I can find)

krmbzds

They removed privacy.resistFingerprinting.spoofOsInUserAgentHeader a while back as well. I find that suspicious.

chrisweekly

I hope Orion (from Kagi) gains more traction and follows through w/ open-sourcing everything. Privacy-first, 0-telemetry, performant, capable... just not OSS (yet).

Squarex

Any info about planned open sourcing? I have not heard about it.

chrisweekly

"Kagi is making progress towards openness by open-sourcing components, Orion as a whole is not open-source and no specific date for a full open-source release has been announced."

squidbeak

An AI sidebar doesn't bother me. But it should be an extension, not an inescapable part of the browser.

netule

I'd love to be able to open up an arbitrary web page in this sidebar. It would be super valuable for research. They can obviously do it, since the AI sidebar also loads a web page, but the functionality is locked for some reason, and vertical splitting extensions are pure jank.

I really wish Mozilla would focus on addressing some of the numerous user feature requests, rather than whatever the current trend is.

Brybry

The tab group work Firefox has done has been mostly great.

The idea that Mozilla doesn't focus on user feature requests seems unfounded? [1]

kwanbix

Yeah, I lived in the Netherlands for five years, so I switched to Chrome because its translation feature is much better.

Now that I'm back in my home country, I've gone back to Firefox, which I prefer from a philosophical standpoint. But there's one simple feature keeping me from using it full-time: the ability to rename windows.

My workflow relies on having one window per project. I name the windows Project1, Project2, Project3, and so on, so it is very simple to find each one.

There are a few Firefox extensions that allow renaming windows, but the names disappear every time I restart Firefox, and they don’t sync across devices.

So, unfortunately, I’m back to using Chromium.

orev

Maybe tab groups would work for you? Windows/tabs are usually (always) named from the <title> html on the web site, and I’m surprised Chrome lets you change that in any persistent way. Firefox tab groups lets you manage things yourself at a higher level.

netsharc

> I'd love to be able to open up an arbitrary web page in this sidebar.

Vivaldi has that. (When Opera got bought out by some Chinese company, one of the original founders created Vivaldi. It's Chromium-based, so Chrome extensions work, and Chrome extensions not using Manifest V3 might end up not working soon).

sphars

If you want to stick with Firefox, then I'd recommend Zen[0]. It has the tiling feature much like Vivaldi, among many other enhancements on Firefox.

NicuCalcea

I was looking for something like that and haven't found a good solution. I like having Claude easily accessible in the sidebar, but I'd also like to add pages like my RSS reader, calendar, maps, etc. rather than having to open them in a new tab or window.

shawnz

Would the split tabs feature that they are currently rolling out work for your use case?

https://windowsreport.com/hands-on-firefoxs-new-split-view-l...

jerrygoyal

If you're not fan of vertical splitting sidebar check out Jetwriter AI. It opens up as an overlay modal and you can use your own API Key as well.

BoredPositron

You can define a custom "AI" provider via about:config. It takes every webpage.

kjkjadksj

Uhh, why not open two windows?

eloisant

Not only that, AI providers shouldn't be a hardcoded list.

Firefox used to be the most configurable, everything plugable browser, what happened on that?

If a 1.0 was released today, would they have a hardcoded list of search engines?

kijin

Exactly. Firefox probably owes almost all of its remaining market share to its extension ecosystem, but it is rotting away in neglect.

First-party extensions are a nice way to test out ideas and features without increasing the core product's maintenance burden. I wouldn't even mind if Mozilla heavily promoted their own extensions, because it would help draw attention to the extension library as a whole.

lofaszvanitt

It should if you try to fly off the radar. Not that Tor browser isn't a fucken emmentaler.

ionwake

I dont know why anyones being defensive about firefox as if they have drawn ire for no reason at all, when in my xp they have done alot of sus stuff, and I hardly know anything about well anything.

NoSalt

Good!

I do not want nor need AI in every single aspect of my life. I mean, I've seen AI hygiene products out there. How does that even work? Don't answer that ... I know it's a marketing scheme, akin to the "HD" craze of five to 10 years ago.

bodge5000

Reminds me of the story of the ice tea company that changed their name to include "Blockchain" and saw their value shoot up a few years ago

culll_kuprey

Why on earth did I waste my life working of clearly the path to success is based on plastering buzzwords in irrelevant places.

ntoskrnl_exe

I'm waiting for the day we get microwaves with an AI that turns them off once the timer reaches zero.

autoexec

Every microwave turns off when the timer reaches zero. It'd be better to have AI that turns it off when the timer reaches one so that I don't have to quickly stop it before the bell goes off. Better yet, a mute function would do the same thing.

blahgeek

Actually it already exists. My microwave have a button labeled “AI” which suppose to run the microwave until it determines the food is ready.

kiddico

If it has a humidity sensor it'll likely work, but doesn't need "AI"

ekianjo

We have had this function for dozens of years in Japan already

bookofjoe

Mine have had that for as long as they've existed.

marcosdumay

Does it send the zero-time notification to a cloud LLM endpoint that will send back a 10 kB JSON that instructs the oven to turn off? (Or not, how could we predict it?)

hbn

What "HD craze" was there from 2015-2020?

raffael_de

"HD" as a marketing buzzterm for products where "High Definition" technically doesn't make sense. Like adding 2.0 everywhere.

hbn

The only example of that I can remember was "HD sunglasses" but I don't recall that ever being a widespread fad. I only saw people ever joke about that.

HD as far as I ever saw it used generally referred to 720p and soon after 1080p. Which is a pretty objective, non-marketing definition. And the timeframe of 2015-2020 seems way off. 1080p was pretty standard by like 2010. YouTube started streaming 4K in 2010.

altairprime

HD GIFs, most likely.

jmkni

The HD craze was more like 20 years ago, you're getting old :)

creaturemachine

Before that was the prefixing everything with a lower-case i craze.

ryandrake

It feels like we are going to need a lot of volunteer effort to help remove all the AI garbage out of all these projects that insist on jamming AI into themselves.

ascagnel_

This week the GZDoom project forked into UZDoom after a maintainer force-pushed AI-generated code into the repo. Thankfully, it failed to compile and other maintainers caught it before it made it out, but the decision to fork came down pretty quickly.

altairprime

Who can afford to volunteer as fork maintainer for a monolithic browser codebase, though?

IT4MD

Agereed. Sadly, we're on the wrong planet, my friend. AI will be shoved into every available orifice and more. It's a great tool for "them" to gather even more info on you to sell to anyone with a handful of nickels.

The last thing any of these masters of the universe will do is leverage AI to make everyone's life better.

Very good news, this would have raised a major red flag for me if I went to use their browser and saw any AI integrations.

BeetleB

The AI integrations, AFAIK, work only if you provide an API key.

icepat

Yes, however it still means that the browser is phoning home to somewhere. To be able to make use of that API key, it has to send some data out. Is that data routed over TOR? Does it even matter given that an API key can be used to deanonymize you?

BeetleB

My understanding (and this may have changed), is that you have to initiate the AI features each time (e.g. clicking on "Summarize This").

But yes, your point is valid. For Tor, if you enter an API key, you could be identified. Still, does the Tor Browser prevent you from installing addons which are no more secure than these AI features? It didn't years ago - not sure if that's changed.

unethical_ban

If you don't put in an API key, does it try to connect?

vee-kay

Did you know..

Mozilla get >80% of its revenue from Google, by making Google Search as default search engine on Firefox.

While Mozilla pretends to be a non-profit, its CEO makes millions of dollars annually.

Mitchell Baker: Stepped down as CEO of Mozilla in February 2024. Her salary for 2023 was reported to be $6.9 million. Laura Chambers: Became interim CEO of Mozilla in February 2024. Mozilla has not disclosed her salary for 2024 yet.

As of October 2025, the average annual salary for employees at Mozilla in the United States is ~$115k.

Not bad for a "non-profit", eh?

Yup, Mozilla and Firefox are surviving (nay, thriving) due to Google.

But Google's hand on the Mozilla tiller, is merely the top of the proverbial iceberg. Google has a monopoly on the browser market, encouraged by Apple Safari slipping down to <14% market share amongst the leading browsers.

Google's Chrome (>71% market share) and the other Chromium forks (>9% market share: Edge ~4.5%, Samsung Internet Browser ~2%, Brave/Vivaldi/etc. ~1%) dominate the browser market. Opera (~1.75% market share) is not a Chromium fork, but it is based on Chromium Project.

https://gs.statcounter.com/browser-market-share/

rchaud

Lots of nonprofits have CEO comp in the millions. Firefox is a large company with lots of employees and tens of millions of users. They have to offer compensation that is somewhat close to market rates to be able to hire people capable of managing that kind of scale. Mozilla isn't funded by individual donations and doesn't charge its users for Firefox, so what does it matter what the execs get paid?

anjel

Non-profits are headed but also staffed with the same ambititious types as for-profit businesses. If you think only Mozilla pays its CEO attractively, you are misinformed. Managerial talent costs, and non-profit CEOs, in my direct experience, use the same lateral pay package comparisons to other non-profit CEOs to justify their comp packages.

The whole point of carving out an alternate rules space for non-profits in a capitalistic economy is that some business functions are both necessary and very unlikely to be profitable.

The assumption that employees would work in non-profits at an uncompetitve wage is a widespread fallacy. In the end a non-profit is either:

1. unprofitable but so necessary it finds subsidies to continue unprofitable operations

2. breaks even

3. runs well enough to generate an operating surplus which by NP tax regs must be either distributed to employees as a bonus or put forward to organisational growth.

In any of these three revenue scenarios, underpaying critical staff is an org death spiral by loss of requisite talent.

CEOs in the US often make much more in the US than other countries, and US non-profit are not nearly immune to the larger forces responsible for that trend.

noir_lord

I did but I don't see FF splitting from Mozilla (by whatever mechanism) either sadly and if you lose the name it becomes hard to get adoption for the forked one - see IceWeasel.

bstsb

that being said IceWeasel is a particularly bad name

noir_lord

I mean the primary image editor in open source land is Gimp (which I had to explain to an ex many years ago when she hopped on my PC) and our main open source source control system is called `git` (funnier if you are British) so open source devs have form for picking bad names :D.

`Git can be a right git` is a valid sentence here.

"Mozilla has reversed course on when the protocol portion (e.g. http or https) of the URL in the URL bar is hidden since Firefox 128. We used to have logic in one of our patches around Onion Services (which are always end-to-end encrypted regardless of the application-level protocol used) to follow whatever Firefox does for https. However, with the latest changes in Firefox, this patch became a bit gnarly to apply correctly so we took a step back and thought to ourselves, why are we even conditionally hiding this from the user?"
