After the controversial news shared earlier this week by Mozilla’s new CEO that Firefox will evolve into “a modern AI browser,” the company now revealed it is working on an AI kill switch for the open-source web browser.
On Tuesday, Anthony Enzor-DeMeo was named the new CEO of Mozilla Corporation, the company behind the beloved Firefox web browser used by almost all GNU/Linux distributions as the default browser.
In his message as new CEO, Anthony Enzor-DeMeo stated that Firefox will grow from a browser into a broader ecosystem of trusted software while remaining the company’s anchor, and that Firefox will evolve into a modern AI browser and support a portfolio of new and trusted software additions.
What was not made clear is that Firefox will also ship with an AI kill switch that will let users completely disable all the AI features that are included in Firefox. Mozilla shared this important update earlier today to make it clear to everyone that Firefox will still be a trusted web browser.
But I don’t trust the CEO at all.
They could save time and efforts and just not implement AI features
This will be like all those times tech companies promised us they aren’t harvesting our data only to find out they were harvesting our data. Years from now we will find out the AI was lurking in the background watching us, learning from us the whole time.
Repeat after me. “There is no such thing as a non physical kill switch”
Funny how companies and applications default to features being auto implemented by default. Baked into the applications.
What happened to having the user select what they want rather then “a kill switch” for an application, whatever that means. Features shouldn’t be on by default. I should be able to turn what I want on and off
“Kill switch” is a bit dramatic. It’s an on or off toggle. Would be funny though to call every toggle a kill switch. “Yeah, using the kill switch on GPU acceleration may help with rendering on some systems.”
“Use the kill switch for preventing Firefox of starting a new session without restoring the old tabs.”
“Kill all of your browser data upon exiting Firefox by enabling the kill switch.”
“Make Firefox your default browser by enabling the ‘set as default browser kill switch’.”
Extended to other UI interaction classes: “You don’t like English? Kill it by using the battle royale language selector to choose only the one language you like.”
I hope librewolf will have it killed by default
CEO : Panik
Why not just ship it without any of the AI stuff and give users the option to install and use it instead of bloating the application? This also confirms that the stuff is essentially OPT OUT instead of OPT IN
The bubble is AI and they want some of that bubble investor money is my guess, so they put optional AI
“On by default unless you run down a setting buried in a menu” is the thinnest type of optional in computing.
the actual thinnest is only having a choice between “yes” and “later”
Have you attempted to turn of AI in Firefox? It’s literally like two checkboxes and it’s off
that’s not about just me. defaults matter a lot.
let’s see what they implement though, their translation engine is nice so far, tbf.
That’s fair, but also if you search AI in the settings it shows you all the options
It’s like saying cosmic is optional on Pop_OS.
Sure, you can rip it out if you really try… but is it really optional?
Have you attempted to turn of AI in Firefox? It’s literally like two checkboxes and it’s off
Flip the script man.
Imagine if enabling AI was like two check boxes and it’s on, for those people who really want it.
Sounds great.
I mean yeah that would be better, I’m not disagreeing
In their defense a very tiny percentage of users even open options and of those an even smaller actually change stuff.
Maybe slighlty different for Firefox as probably more power user use it than other random programs. But basically if something is not enabled by default, it doesn’t exist.
And also … will the kill switch turn off the AI entirely … or partially? Since the AI system is baked in, will elements of it still operate in the background even if you turn off the switch?
Not sure what you mean by “will it operate in the background”? The current (and planned) features collect no data. They “operate” when you use them. Disabling them will remove them from the UI.
lol … so they won’t change how they function … just remove them from sight
out of sight, out of mind, right?
Whenever I trust big corporations … or even big organizations with a lot of power in their hands … it’s never usually good for common people like me and you.
It’s an open source browser.
The publicly available code is the most verifiable system of trust you’ll find.
No, they won’t be used at all, and will be hidden from view, if turned off.
What he wrote doesn’t seem ambiguous on this at all. But we’ll see.
So you agree that it will be baked in and impossible to actually turn off. Yep.
Otherwise, they would have made it an extension, right? If it’s optional, it needs to actually be optional … that’s what am extension is. That’s the whole point of them.
No
You can not push the button that says AI.
You can also hit the kill switch that completely removes that button.
That’s opt-in enough.
If it starts reading pages or doing things without you pushing a button, that’s an issue.
If it starts reading pages or doing things without you pushing a button, that’s an issue.
And therein lies the rub. The question is whether or not people trust that it won’t be doing that regardless of whether or not you hit the kill switch.
Good thing it’s open source and we’ll immediately see that they aren’t doing the thing you’re claiming.
No, you don’t have to trust anything. It’s open source, you can read the code.
And if you’re feeling paranoid, you can compile it yourself.
Because they’re counting on people who know nothing about technology using the AI stuff when it’s placed in front of them.
This should just have been an extension. Having this as a core integration makes the browser have more surface area for attack.
If compromised, it won’t be an easy fix like disabling/removing an extension.
Looks like execs behind closed doors are just trying to water down the Firefox brand until it’s hollow and then jump ship.
All AI features will also be opt-in. I think there are some grey areas in what ‘opt-in’ means to different people (e.g. is a new toolbar button opt-in?), but the kill switch will absolutely remove all that stuff, and never show it in future. That’s unambiguous.
Sounds like they will be opt in, not opt out
No, go deeper into that mastodon thread.
The dev has a really hinky defention of “opt-in” thats basically “yes we push all this on by default and realize it will be the norm for most of our users because of that, but you technically dont have to interact with it so thats opt-in.”
Somehow, eventually having a buried menu option that “opts out” of AI is also part of how it will be opt-in as well? Its a self serving mess of rationaliztions and doublethink, no matter the claim on the tin.
I mean yeah, that’s a fair point, and the dev said that themselves, that the definition of opt in is ambiguous. The definition they seem to use is that AI won’t run unless you explicitly tell it to, and I think that’s ok. There’ll be a button that you can press to do some AI action and you can hide it using the kill switch.
I do hope the kill switch isn’t hidden behind 5 layers of menus
Thats not ambuguity. AI will be opt out in firefox, which is them abandoning core principles like user choice and privacy.
They can do that, but playing like they aren’t by redefining well established terms in UI/UX is disengenious, and cuts right through the “we will earn your trust back” messaging made by the same dev.
I think it’s quite clear there’s ambiguity (hence this discussion). How would you define opt in? Should a user not even see the button for an opt in feature?
I think the big defining question is what will the AI features that they will implement do exactly and how will they run. If it’s something that runs in the background (even as unintrusive as the summaries on a search engine like DDG), then it’s opt out by default as it’s constantly running whether you want it to or not. If it specifically and exclusively runs when you hit the button to activate it and doesn’t run at any other time, then I’d say it’s unequivocally opt in. And regardless of what a company says that their software will do, at this point I won’t believe it until somebody has done a full teardown and discerned what exactly it does behind the scenes. I’ve seen enough nonsense like the Epic Games Store accessing your browser history and recording keyboard inputs or whatever the other absurd incident was.
Nah, I think it should be optional. Some AI features may even be useful — like an AI script to get rid of AI slop or something, idk.
In my opinion there is no ambiguity at all.
Opt-in means that the feature is disabled by default and until the user enables it. This is NOT what Firefox will be doing.
Opt-out means that the feature is enabled by default and can be disabled by the user. This is what Firefox will be doing.
Whether the user actually uses or not the feature is not a factor in determining if it is opt-in or opt-out.So if you never press the AI button, it’s never enabled. It is opt-in in the strictest semantic sense.
What you say here applies for things that run automatically, like the anonymous usage reports, which is opt out, not for things you activate yourself.
A feature that will not do anything unless you explicitly press a button to start using it is quite literally opt-in, though? Opt-in doesn’t mean “I won’t even know the feature exists without hunting through the settings”. It just means that it won’t start doing things without your consent. Presenting a way to provide that consent in a more visible place than buried deeply in the settings does not make it opt-out. It might be a bit annoying to you, but it has no effect on your user choice or privacy, especially if there’s also a way to globally hide it and any other features like it, including new ones that might be added in the future.
Let’s have a look at how it works now, so we don’t need to speculate.
When I configured Firefox for AI, I got to choose my LLM of choice. I chose Claude. Now, if I select some text, I get a context menu option that says “Ask Anthropic Claude”, which branches into these options:
- Summarize
- Explain
- Quiz me
- Proofread
- Remove Anthropic Claude
Notice the last one? That’s not a “buried” option. That’s as front and center as the options to use it. Mind you, if I decide to not use it, then nothing happens. The only thing that’s changed is that I now have an optional shortcut for LLM features that open in a sidebar instead of a new tab.
Oh, the humanity.
I don’t see why there is a big outrage. Sure I’m not a fan of the AI features and I certainly will disable them but it’s tot like they’re forced upon me. Some people like (want) AI in the browser and good for them, this makes the browser better and easier to use for them. For me, it doesn’t change my experience at all
(Commented this separately on purpose)
Come to think of it, I do enjoy the translation feature in Firefox
The alt-text tagging is pretty amazing according to my sister (blind), too.
I’ve been thinking the same thing. The online tech community is a very small part of a much larger pie and they need to serve multiple audiences. As long as it can be turned off and truly be off, who cares?
People don’t trust that it can be truly turned off and that it won’t act maliciously in some way. That’s really the crux of the whole saga. We’re at a point where phone companies are getting survey results that say that 80% of users either don’t care about AI nor use it or find that it actively makes their user experience worse.
Did those people forget this is am open source browser and they can actually check it’s doing what it says it’s doing?
And if they’re that paranoid that they don’t trust the pre-compiled binaries, they can just compile them themselves.
This discussion is completely absurd to me.
Quite honestly, I don’t think the average person even knows what open source means. They just know that Mozilla, like every other company, is shoving AI into their product, and that AI has either been useless or actively harmful to their user experience.
Many people love AI, I have a lot of acquaintances who actively seek out the best “AI browser” whatever that means. It makes sense for mozilla not to fall out this bandwagon just yet.
That’s nice but it’s not good enough. There needs to be a compile flag so the AI code isn’t even included at all.
Well they’re clearly not taking it all that seriously as it should be an Opt-IN feature, not an Opt-Out. They’re banking on a majority non tech savvy userbase to not even bother disabling it. fine, whatever, that’s on the user.
But it’s just more Firefox bloat that I have zero desire to deal with. If I wanted bloat in my browser I’d go use Vivaldi.
Or they could just ship it without the AI
They could save themselves all that bullshit by just not bothering with any of it!
Is there nobody with sanity left? This has blown up so much the user base clearly does not want it. Focus your efforts elsewhere. You gain marketshare by putting users first. Also fuck markets.
If all Firefox users donated to Mozilla it could work. Alas, we don’t.
I probably would, if the organizational structure and its spending focus(es) weren’t so fucked up. They have been spending insane amounts of money on bullshit like AI instead of core browser features, and their leadership has extremely high wages for something that should be a non-profit open source organization. And it has been like this for years at this point.
Their CEO makes more than I think CEOs should earn in general, but the rest of their executives earn relatively normal to low salaries for their roles and the sector.
Non-profit doesn’t mean everyone works for free.
Well to be fair they only had that or onlyfans to get paid to sit there playing with themselves.
They’d have done less damage going for the OF option.
I mean, I bet they’d make a killing off of Firefox themed thigh highs…
You can donate to Mozilla, you cannot donate to Firefox.
Which is probably a good thing. I appreciate projects like Thunderbird as well.
No money you donate to Mozilla Foundation goes to either Firefox (MozCorp) or Thunderbird (MZLA).
They are separate entities.
That’s what I call reverse reasoning.
You sound like mozilla is adding because of lack of donations meanwhile correct is there is lack of donations because features nobody asked for like AI.
Pretty much this.
They are making market based decisions because they have to, and all the users bitching and moaning about them making financially driven decisions don’t donate anyways.
Then let’s
How? Where? I’ll donate, take my money, and ads a voting system where paying users can vote for the next features
https://www.mozillafoundation.org/en/donate/ if you’re actually interested in donating.
I would donate if I ever had spare money but I never do.
$5?
Make fun of the poors yeah?
No, I just don’t believe they really can’t spare $5.
Maybe they can’t but I’m skeptical.
They? You mean me? Lmao you are replying to the same person.
A very vocal portion of the user base, but we don’t actually know what absolute portion cares. I’m personally unlikely to use possible AI features outside translation, but Mozilla has generally done enough that I don’t feel particularly worried they’re going to mess with my privacy or force me to use a feature I don’t want.
They could do a survey amongst Firefox users about what they want.
But if the result is anti-AI they can’t claim anymore that they weren’t aware of their users opinions.
The issue is that there aren’t many of us Firefox users left, so asking us while FF wants to get NEW users to expand the market share (which is badly needed, so they do not lose their seat at the table regarding web standards, and to make them less dependent on googles payments) is not helpful at all.
As long as i can switch it off with one click, i couldn’t care less and will continue using FF, but as you can see many existing users will bitch and moan even if it’s just one click.
so asking us while FF wants to get NEW users
This is a balancing act and Mozilla behaves like an elefant in a porcelain shop right now. Worst case they loose their current users without attracting new ones.
existing users will bitch and moan even if it’s just one click
I’m one of them. Why not make it one click for people who want it instead?
Worst case they loose their current users without attracting new ones.
And where to?
Ladybird, Servo and Floorp are all not useable as a daily driver and will take years to get there (and btw, the ladybird guy is a major shithead and last i heard of Servo was that they were going to cater to the embedded market, not a full blown browser).
Firefox forks can do what they want, even switch off the AI button, but i’d still say they help keeping the browser engine itself afloat, because they still depend on Firefox - there’s not one fork with enough dev staff to keep up. That leaves us with chromium based browsers and safari. I’d say the commitment to the current userbase to make the changes optional is good enough to keep most of them.
I ’m one of them. Why not make it one click for people who want it instead?
I’d put current Firefox users much more in the department of “able to find the settings” than the vast majority of users. The majority wants something that works with everything they throw at it out of the box without rummaging through settings.
And where to?
If both noteworthy browser engines are made by companies who make decisions against their user’s interest I might as well switch to the one with higher development budget.
The majority wants something that works with everything they throw at it out of the box without rummaging through settings.
And where does AI come into play here? It’s not like a browser without AI doesn’t work.
Chill out. It’s literally just a sidebar for your LLM of choice.
Don’t like it? Don’t use it.
Don’t want it to clutter up your context menu? The same menu contains the option to disable it. Boom! Problem solved.
Gonna use Chromium-based with no µBlock because your feelings got hurt? Have fun.
At least Firefox isn’t an extension of the worlds largest ad company, no amount of dev budget can fix that.
Context aware search, summarizing in side view or importing an agent directly from a repository into your browser are things that come to mind without much thinking, and i am not a developer.
We need valve but for browsers.
Funny. That’s exactly what Mozilla used to be.
Yup, RIP
Ehh, I’d pass on Ladybird. I’ve been donating to Servo myself.
Ladybird I follow since it’s an entirely new browser engine and can help restore a little democracy to the web, but why Floorp? I’m looking through its website and it seems to be a more customizable Firefox, which is nice, but doesn’t seem particularly revolutionary (and forks of Chromium/Firefox are kinda a dime a dozen).
Floorp misses the mark for me. Waterfox and librewolf seem to be a better fit for most people.
Always celebrate more options, though. I hope ladybird does well and doesn’t shit the bed the moment it gets some market share.
These days I’m tempted to just write myself a super minimal front end to Servo though because I don’t want 90% of what modern browsers ship with.
No idea why Floorp has garnered attention but other seem interested.
It seems to me that the issue is how we consume the web versus games: We’re used to pay to play but not to browse the internet. Valve is able to make money without relying on affiliations or donations.
Getting stuck on Lemmy can get us into an echo chamber. A lot of the mass public actively uses AI and may even appreciate these features.
[citation needed]
This sounds like an opinion from the LinkedIn echo chamber.
According to top results for a few searches,
ChatGPT has 700 million weekly active users, as of September 2025.
Gemini has 350 million monthly active users, as of April 2025.
ChatGPT is the number 1 app on the Google Play top downloaded apps currently.
Some numbers may be slightly inflated for a number of reasons, but another source is speaking to people IRL. I often overhear conversations mentioning ChatGPT or AI in general.
“AI bros” are definitely cancerous but a lot of average consumers do in fact use AI frequently
