Mozilla is taking a different path from its browser rivals by introducing an “AI kill switch” in Firefox, giving users full control over artificial intelligence features.

The option will arrive with Firefox 148, scheduled for release on February 24.

Mozilla has confirmed that Firefox 148 will include a built-in AI kill switch, allowing users to disable all AI features in the browser at once.

The feature is designed for users who prefer a more traditional browsing experience and are uncomfortable with the growing role of AI in modern browsers.

In addition to the global kill switch, Firefox users will be able to manage AI tools individually.

These include translations, AI-generated alt text in PDF files, AI-powered tab grouping, link previews, and the AI chatbot available in the browser’s sidebar. Users can choose exactly which tools to keep enabled—or turn them all off entirely.

Firefox takes different approach from rivals

Firefox has long attracted users who are wary of the direction taken by Google Chrome and other Chromium-based browsers.

As competitors increasingly integrate AI across their platforms, Mozilla’s decision positions Firefox as a browser that prioritizes user choice rather than default AI adoption.

Backlash over AI features in 2025

Mozilla faced criticism in late 2025 after announcing plans to introduce AI features into Firefox.

Although the company stressed that these tools run locally on users’ devices and do not send data to cloud servers, many long-time users expressed concern about AI’s presence in a browser known for privacy and independence.

The announcement of the AI kill switch has been met with a positive response from parts of the online community.

On Reddit, one user commented that the feature “says a lot about the future state of AI when the most requested feature is to disable it.” Another user noted that Mozilla appeared to be “actually reading the room.”

For many Firefox users, the ability to completely block AI feels like a sensible compromise.

Mozilla’s move acknowledges skepticism within its user base while still allowing those who want AI tools to use them. The update may help restore confidence after concerns raised by earlier AI announcements.
