If your ideal browser experience involves as little AI as possible, Mozilla is finally giving you a way to shut it all off on Firefox. The company has confirmed that an AI “kill switch” is coming to Firefox Nightly builds first, before rolling out to everyone on February 24 with the release of Firefox 148.
Once it lands, users will be able to disable every AI-powered feature in the browser with a single setting. Mozilla’s move comes at time when many AI browsers are racing to add more automated tools, whether people ask for them or not. With Firefox, you can use AI if you want it, but you do not have to live with it if you don’t need it.
Inside Firefox’s new AI control settings
Firefox already includes several AI features, and the new AI controls bring all of them into one central place.
Enabling the AI block will switch off chatbots in the Firefox sidebar, along with on-device tools for translating web pages, intelligently grouping tabs, surfacing key points in link previews, and adding accessibility descriptions to images in PDFs.
At the same time, users can still choose to turn these features on or off individually, rather than disabling everything at once. Mozilla says the switch also stops all AI-related prompts and reminders across the browser. That means no pop-ups nudging you to try a chatbot or experiment with AI features later.
Users can still turn individual AI tools back on if they want, and once preferences are set, they will stay in place across browser updates.
Back in November, the Mozilla Foundation announced an upcoming AI Window, a separate space that lets users access their preferred AI chatbots and agents. That feature is currently limited to a waitlist and is completely opt-in.
At a time when AI is being added everywhere with few off switches, Firefox’s approach stands out by giving users a clear choice instead of forcing new features on them.
