Overview
Mozilla announced that Firefox 148 will include a new control allowing users to turn off every generative AI feature built into the browser. The change responds to growing frustration over AI tools being enabled by default without clear opt‑out options.
What AI Features Will Be Disabled
When the setting is activated, the following AI‑powered components will be blocked:
- AI‑enhanced search suggestions
- Chat‑style assistance in the address bar
- Content generation tools such as “Compose” and “Summarize”
- AI‑driven image and video enhancements
In addition, Firefox will stop displaying pop‑ups or notifications that promote existing or upcoming AI tools.
How to Use the New Setting
The option will be located in Settings → Privacy & Security → AI Features. Users can toggle a single switch labeled “Disable all built‑in AI features”. The change takes effect immediately and does not require a browser restart.
Release Timeline
The feature is slated for the stable release of Firefox 148 on 24 February 2026. Nightly users may encounter the setting earlier as part of the development channel.
Implications for Users
Providing a straightforward opt‑out gives privacy‑focused users more control over data that would otherwise be processed by AI services. It also sets a precedent for other browsers that have begun embedding AI capabilities.
