Firefox Developer Says a Global "AI Kill Switch" Is Planned for Upcoming AI Features

Posted on Edited on
A Firefox developer says Mozilla plans a global setting to disable all AI features and keep them hidden, aiming to address backlash over the browser's AI pivot.

Quick Report

A Firefox developer posting from the official Firefox for Web Developers Mastodon account says Mozilla plans a browser-wide option to completely disable all AI features. The message describes an internal "AI kill switch" concept that would remove AI functionality and keep it from reappearing unless re-enabled manually.

The clarification follows user backlash after Mozilla discussed steering Firefox toward an "AI browser" direction. In the post, the developer also says AI features will be opt-in, while acknowledging that "opt-in" can be interpreted differently (for example, whether a new toolbar button counts).

A global off switch is a meaningful commitment if implemented cleanly, because it sets a stronger expectation than scattered per-feature toggles. The key detail to watch will be scope: whether the switch covers all AI-related UI and services, including anything that might otherwise ship enabled by default.
