Firefox dev clarifies there will be an AI 'kill switch'

The saga continues! A Firefox developer has taken to social media to note there will be some sort of "kill switch" to completely remove AI features in the wake of the news about more AI features coming along with the new CEO.

Speaking on Bluesky and Mastodon across multiple posts that I'll quote below to save you clicking around they said:

Something that hasn't been made clear: Firefox will have an option to completely disable all AI features. We've been calling it the AI kill switch internally. I'm sure it'll ship with a less murderous name, but that's how seriously and absolutely we're taking this.

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.

I'm not asking for faith in our direction - the thing I love about the Firefox community is how open, honest, and technical it is.

But I do ask that you don't have the opposite of faith. Like, try not to be determined that we're going to do the wrong thing here.

I hope we can (re)gain your trust here. I don't personally work on this stuff, but I'll try hard to answer any questions you have. And other than that, I'll get back in my lane, and stick to web platform stuff. - Jake (@jakearchibald.com)


Personally, it all still makes me very uneasy. The list of problems with generative AI is endless. I'm happy they are committed to a simple switch to turn it all off, but the fact that they're still pouring resources into AI is a problem. A browser simply doesn't need to have a ton of AI features bloating it. To me this feels like Mozilla are just doing what every other company seems to be doing - chasing a ridiculous bubble for marketing and buzzwords.

What do you think to this? Let us know in the comments.

Quoting: sarmadIf everything is opt-in as this dev says, then I think their new CEO simply gave the wrong message by calling it an AI browser.
So the CEO of Mozilla has zero idea about the product they are managing. Yet we have to trust a dev that says " I hope we can (re)gain your trust here. I don't personally work on this stuff, "

So one dev who doesnt work on it and a CEO who called it an Ai Browser.

Im getting serious " Everything Computer " vibes here.

"We've served you raw sewage with your meal, but don't worry! It's in a separate glass in case you don't want it."

Even if we charitably assume that there won't be any caveats with it being opt-in or with the kill switch, it still reflects poorly on Mozilla that they're even pursuing this garbage in the first place.

Quoting: no_information_hereb) Vivaldi has made a public no-AI statement. I prefer FF, but a good alternative is sitting there waiting.
I would be careful about Vivaldi as the CEO has made some weird political statements in the past - though I'm no longer able to find any of them at all potentially due to search being scrubbed, as for Proton (this being relevant because Vivaldi ships free Proton VPN) I'm not sure of it sometimes but personally I don't use their services except email.

we cannot have the opposite of faith or the reverse. So um... Quantum faith ?

IMHO the issue with Firefox "adopting AI" is way overblown. Yes, AI is not great (especially if it's done with speculative bubble and cash burning by big-tech) and it's questionable ethics wise but… sometimes it's usefull and people do use it…

Also what's the alternative? Crappy reskins of chromium? :/

At least Mozilla seems to listen and reacted to the backlash. Imagine google doing that…
