Firefox will add an AI "kill switch" after community pushback

[Alfonso Maruccia]

Editor's take: Mozilla has a new CEO, and a very original idea about the future of Firefox. The open-source software is set to embed nearly every kind of AI feature in the near future, but the community isn't exactly behaving like a bunch of happy bunnies for the change.

Mozilla Corporation recently introduced Anthony Enzor-DeMeo as its new CEO. The company, which is a wholly owned subsidiary of the nonprofit Mozilla Foundation, is tasked with coordinating the development of the Firefox web browser and other internet applications. In his introductory message, Enzor-DeMeo said several things that raised concerns about the project's future.

The new CEO said Firefox would evolve into a modern AI browser, growing into a broader ecosystem of trusted software. People still trust the Firefox brand, he argued, which is why Mozilla should always be transparent about how its products use data and handle privacy. AI should always be a choice, Enzor-DeMeo stated, but Firefox must still pursue monetization.

The shrinking number of netizens who continue to use Firefox did not welcome the idea of turning the open-source project into an "AI browser." Chatbots, LLMs, and other "modern" AI features are black boxes that offer little transparency. AI or agentic-based browsers have also been widely criticized as a major security risk to the broader internet ecosystem.

Vivaldi and other browser makers are pushing back against this aggressive integration of AI features, and many alternative browsers based on Firefox have taken a similar stance.

Waterfox developers said their browser will not include any LLM, "full stop," while Pale Moon developer Moonchild said it will not add any kind of AI based feature anytime soon.

Enzor-DeMeo's message triggered significant backlash from a portion of Firefox's user base, prompting some Mozilla developers to respond. Firefox programmer Jake Archibald recently said that an upcoming version of the browser will include a "kill switch" to completely disable all AI features, and that the team is taking the issue seriously.

In response to an open letter arguing that Firefox doesn't need AI but leadership that listens to users, Enzor-DeMeo said browsers must "please" every kind of internet user.

And some of these users are likely going to enjoy their AI slop without even thinking about it. Regardless, the CEO confirmed that an AI kill switch is coming to Firefox in the first quarter of 2026.

Their developers also tried to gaslight everyone into thinking firefox's implementation is "opt in" while asking for people to trust them. These developers hate you and think of you as children.

I think I'll be trying to switch to Waterfox on desktop instead, thanks. I'd switch to it on mobile as well but unfortunately there isn't an iOS version.

 

[Primey]

Gonna switch from firefox to waterfox. Thanks for mentioning it

Noone is asking for AI features. People are literally asking for the opposite of this. opt-out gives plausible deniability to the company but they're ruining a perfectly good product that functions as advertised.

Enshitification. CEOs don't just "get hired". Everyone who hired him needs a large boot up their *** when they leave the building

Damn. Using Firefox for more than 20 years and somebody is going to break it. It's sad that I will have to switch to Waterfox or Vivaldi after a useless gimnick installation. The guy is blind, there already are AI browsers for kids.

For what it's worth, I turned off the ones I don't want fairly easily.

Mozilla did include a locally run translation feature that I've used time to time. Though, not sure why it's not more automatic like Chrome's (not that I trust Google's implementation all that much).

This bodes very badly for the future of Firefox.
Most of the people that use it, are advanced users that want privacy and flexibility.
Adding this AI slop will push most people away and further reduce Firefox's market share.

It wouldn't be a problem if I had to turn that on. If it's on by default and I have to turn it off, that's crap. I hope waterfox is already stable enough and in opensuse repos.

Ultimately what Mozilla wants is money. They must be the most money hungry nonprofit I've seen since the last time I went to church. Yes, I'm aware they are two entities. One exists to feed the other.

After push back? THAT WAS THEIR VERY FIRST POINT which somehow every outlet forgot to quote, because gotta have them clicks.

“AI should always be a choice — something people can easily turn off."

That’s how it all started, they’re literally the most humane of them all, yet people keep losing their sh*t ever since.

And I will stay on Librewolf

Where is my choice to have a browser not bloated with AI trash?

Mozilla could have made this an optional extension for those who want AI integration, but no, they had to force it in by default while graciously allowing you to turn it off (until a future update when it is force on permanently of course) then pretend like it was opt in to use it.

How does a switched off feature "bloat" your browser?

Can you name just ONE mainstream browser that made a definitive statement that they'll never ever implement any AI feature?

There isn't any. They're all doing it. And unlike Firefox, they didn't make it clear that you'll always have the option to turn them all off. It'll just creep in happily.

The way every media outlet (and their enraged commenters) spin this story to make Mozilla look like the bad guy here while the exact opposite is true is just astonishing.

I switched to brave a while ago and it’s way better. No YouTube ads. Everything just works.

This is an understatement of serious proportions. AI has no place being built-in to browsers or anything else.

 

[human7]

The worst part about Firefox is Mozilla. Has been for some time. I still use Firefox, many years ago I used Waterfox. If Waterfox has a strong developer community I might try them again if Mozilla doesn't change course.

 

[umeng2002]

... which resets every update.

That is how Microsoft works. Mozilla doesn't do this kind of thing.

 

[Tantor]

Note that DeMeo did not discuss a kill switch. That came from a programmer.

A kill switch is not good enough. The code is still in the browser waiting to be activated remotely.

Why not make it a plugin/extension? That way the user can choose.

DeMeo reminds me of many other CEOs who eventually ended up compromising or destroying their company. I suggest that most of them are intentionally placed there to do that very thing.

 

[Tantor]

True. MS is brutal.

But why put AI in the browser by default? Why not make it an extension?

The developers have no saying in main decisions on how a product is made, they mostly execute the orders of higher ups(the owners), in this case Mozilla Foundation which in turn get money from their higher ups/investors(no matter their form), in this case Google.

When I switched to Windows 11, I noticed all of the AI stuff and was not impressed that my system felt a bit slower than with Windows 10. I just got rid of anything AI in my Windows 11 Pro and it is faster again.
The only program so far that was not happy was Steam but I am sure a file was removed it wanted because after letting Steam do a self-health check it is working again and is a lot snappier than it was before. I quit using Firefox years ago.

Can anyone recommend a desktop browser that’ll download from Wix websites? Aloha allows downloads on its mobile browser but not the desktop iteration. Thank you.
