Mozilla has confirmed that upcoming versions of Firefox will include a global control that allows users to completely disable all artificial intelligence (AI) features in the browser. The confirmation comes following community concern surrounding Firefox’s planned AI integrations and their potential impact on privacy, performance, and user control.
The feature, referred to internally by Mozilla developers as an “AI kill switch,” is designed to act as a master setting that shuts off all AI-powered capabilities across the browser. Mozilla has emphasized that this will not be a partial toggle or limited opt-out, but a comprehensive control affecting every AI component built into Firefox. The final public name for the setting has not yet been confirmed.
Something that hasn't been made clear: Firefox will have an option to completely disable all AI features.

We've been calling it the AI kill switch internally. I'm sure it'll ship with a less murderous name, but that's how seriously and absolutely we're taking this.

The clarification was shared after ongoing discussion among Firefox users, with many raising concerns after Mozilla announced broader AI plans for the browser.
Their response indicates a commitment to ensuring AI remains optional, allowing users and organizations to run Firefox without any AI functionality enabled if they choose.
While Mozilla has not yet provided a detailed technical breakdown of how the feature will work, the company has stated that the control is being treated as a core part of the AI rollout rather than an afterthought. Additional details, including release timing and the full list of AI capabilities that will be included in future Firefox builds, are expected to be shared closer to launch.
Mozilla continues to position the move as part of its long-standing focus on user choice, transparency, and privacy which have historically shaped Firefox’s development.
