Firefox Will Give Users an AI Kill Switch for Better Privacy

Key Findings:

Mozilla is releasing Firefox 148 on February 24, 2026, which introduces a dedicated AI controls section in the desktop settings.
This includes a "global kill switch" that allows users to opt out of AI features entirely by flipping a single toggle.
Turning off AI features stops the browser from sending data to external companies for processing through API calls.
Users can also customize which AI tools they want to keep, such as the sidebar chatbot, while disabling other features.

Background

AI has become increasingly prevalent on websites, with features like chatbots, translation tools, and tab grouping. However, not everyone is comfortable with the amount of data being shared and the constant prompts to try new AI-powered tools. Mozilla has been listening to these privacy concerns and is now giving users more control over AI in Firefox.

AI Controls and Kill Switch

The upcoming Firefox 148 release will include a new section in the desktop settings dedicated to managing AI features. The centerpiece of this is a toggle called "Block AI enhancements" that acts as a global kill switch. Flipping this switch will disable all current and future AI tools in the browser, cutting off any data being sent to external companies.

Customizable AI Experience

For users who don't want to go completely AI-free, Firefox 148 will also allow granular control over which features are enabled. Options include keeping the sidebar chatbot, while disabling other AI-powered tools like tab grouping or link previews. The goal is to let people pick the AI functionality they find genuinely useful, without being overwhelmed by constant prompts.

Testing and Feedback

Before the official launch, these new AI controls are being tested in the Firefox Nightly early access program. Mozilla is also gathering feedback through their Mozilla Connect community hub to ensure the feature strikes the right balance between functionality and privacy.

Conclusion

By giving users a straightforward way to disable AI features entirely or customize their experience, Firefox is empowering people to take back control of their browsing privacy. This "AI kill switch" could set an important precedent, and I hope other browser makers follow Mozilla's lead in putting users first when it comes to emerging technologies.
