Mozilla is testing a new “AI Controls” section in Firefox for iOS, visible in TestFlight builds. It includes a “Block AI Enhancements” switch. In testing, turning it on marked Page Summaries as “Blocked” and removed access to the feature, even when it had been enabled earlier.
Firefox on iOS already includes AI features such as Page Summaries, which generate quick summaries of web pages. Mozilla is now working to bring AI Controls to iOS. The new section appears under Settings, where users can access the “Block AI Enhancements” switch.

The control works at a system level: it does not just hide options, it stops AI features from running across the app. Individual controls, such as Page Summaries, become inactive, and the feature cannot be used anywhere in the browser. When the switch is on, Firefox also stops showing prompts or new AI features tied to these tools.
Firefox already offers similar controls on desktop. Bringing this to iOS gives users a clear way to manage AI features in one place instead of handling them one by one.
This also sets Firefox apart from Chrome, where AI features are spread across different parts of the browser without a single global off switch. Firefox groups these controls into one setting with a clear on or off state.
One detail stands out: the setting states that on-device AI models are removed when features are blocked. This suggests the control also affects on-device AI components, not just the interface.
Firefox’s AI Kill Switch is still in testing in the iOS beta. It is not enabled by default and is hidden behind a flag. There is no confirmed timeline for release.
