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.

    There should never need to be a “kill switch” for a feature the developers have full control over.

    Just make it opt-in. An AI kill switch makes me think that they’ve got a setting that will block all known AI interfaces and generated content, which is not what this does.

    Moz: We’re an AI first browser. There’s AI in everything now!

    Everyone: Boooo *uninstalls*

    Moz: We’re not an AI first browser. We’ve added these control features so you can reduce the AI.

    Alternative interpretation: the CEO had the focus on pushing the imaginary game-changer and so the controls came later.

    I’ve always seen “kill switch” being used in a negative tone, so with how the headline is written, it sounded like some AI feature that could kill the browser itself was implemented.

    I’ll use it, but I know that doing so will put me on some sort of asshole list and you will fuck me over.

    And I’m fine with that DO IT put me in the alligator camp or whatever, I’m done and done
