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.
As a 10-year FF user, do you have any recomendations to what to switch to?
I tend to like Zen browser. It looks and feels a bit different, but to me that feels refreshing.
Waterfox if you want something that still feels like a modern browser, LibreWolf if you don’t mind having stricter defaults. If you want the nuclear option, Mullvad browser is good, it is very inconvenient thoygh. At least for desktop. On mobile I use Vivaldi/Fennec/Vanadium depending on need
I went to Librefox. It has some harsh defaults that I ended up tuning, but so far it works well. Could just port over bookmarks and such.
I haven’t personally yet, but a lot of people suggest switching to LibreWolf on PC and to either Fennec or Waterfox on mobile. At least on Android, since I can’t be bothered to look up the availability on iOS.
on android ironfox is more similiar to librewolf
