Mozilla finally landed today the long-anticipated AI Kill Switch controls for Firefox, which let users strip the open-source web browser of any AI-powered features, and you can test it right now in Firefox Nightly.
In December 2025, when Mozilla appointed its new CEO, the company developing the popular Firefox web browser revealed that it was working on an AI kill switch that would let users completely disable all the AI features that had been included in the past few releases, estranging more and more loyal users.
Now, the AI kill switch is finally a reality as it landed today with the latest Firefox Nightly update. The implementation is called “AI Controls” and can be found in Firefox’s settings as a standalone section. From there, users can toggle a setting called “Block AI Enhancements” to remove any AI features.
They should never have rolled out any of these AI features without this already implemented. I think it really speaks to their priorities that they rolled it out in this order.
Mozilla’s CEO also recently said they would be building new products based on pre-established trust. I think they got their chronology wrong on that too…
Right, what trust? The trust they lost by putting dumbass MBAs in charge who don’t know shit and chase short term profits over sustaining a healthy community?
I’m not going to argue for AI features in Firefox, but I’m curious which features you feel are a priority?
I think you misunderstood what I said, or perhaps I wasn’t clear. I’m saying the killswitch should have been in place from day one when they started implementing ai features.
That said, Mozilla seems to fundamentally misunderstand their market. The type of people who use firefox are generally pretty tech-savvy, and care about things like privacy and control over their experience. Rather than hone in on features that their users want, they have hitched their wagon to the ai hype train in an attempt to favor curry with the masses.
Right. Like what features?
Improving webapp functionality rather than stuffing more and more AI down our throats, for instance.
I dunno about that guy. I’d like proper PWA support. Better VR integration. Both in Linux.
I’m all onboard with PWAs. I’m super disappointed they have so little love in general. Web tech is great locally when it’s not wrapped in electron.
If you’re a developer, have you worked with Wails? It’s like Tauri (rust) but in Go(lang).
Full profile sync would be nice
What parts of the profile aren’t synced?
Search settings, UI customizations, vertical tab settings, extension settings all come to mind.
If i didn’t have to redo all my customizations on a fresh install, I might actually cry tears of joy (i like to try different os and write my laptop regularly, so this is a legitimate annoyance for me)
A few bug/glitches I noticed and performance improvements are always welcome (I don’t think running ai services and integrations will improve performance)
Off the top of my head:
would all be significantly more useful than any ai features the devs are currently working on.
I like all those!
