Mozilla is giving Firefox users unprecedented control over artificial intelligence features with the introduction of an “AI kill switch” in Firefox 148, set for release on February 24. This feature allows users to disable all AI tools in the browser with a single setting, offering a browsing experience free from AI if desired.
The global AI kill switch is complemented by options to manage AI tools individually. Users can selectively enable or disable features such as translations, AI-generated alt text in PDFs, AI-powered tab grouping, link previews, and the AI chatbot available in the sidebar. This level of customization ensures that users retain full authority over which AI functions they wish to engage with.
Mozilla’s approach differs sharply from competitors like Google Chrome and other Chromium-based browsers, which are increasingly integrating AI by default. By prioritizing user choice, Firefox positions itself as a browser that respects privacy-conscious users and those cautious of AI adoption.
The move comes after a wave of criticism in late 2025 when Mozilla announced plans to introduce AI features. While the company emphasized that these tools run locally and do not transmit data to cloud servers, many long-time users voiced concerns about the presence of AI in a browser celebrated for independence and privacy.
The AI kill switch has been welcomed by parts of the online community. Discussions on Reddit highlight positive reactions, with users praising Mozilla for listening to feedback and offering the ability to disable AI entirely. Many see the feature as a sensible compromise that balances innovation with user control.
By providing both full and selective control over AI, Mozilla acknowledges skepticism while accommodating users who wish to benefit from AI enhancements. Firefox 148 reinforces Mozilla’s commitment to putting users first, giving them the freedom to choose how—or if—AI features influence their browsing experience.
