Mozilla has implemented the long-anticipated Firefox AI Kill Switch controls that strip the web browser of any AI-powered features.

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.

    Off the top of my head:

    • better/more consistent sync
    • container windows
    • setting a default container for ctrl+t (and maybe shortcuts for other containers)
    • a more user-friendly version of about:config
    • more control for automatic data deletion aside from manual and when firefox closes (e.g. delete history+cookies older than 30 days)

    would all be significantly more useful than any ai features the devs are currently working on.
