Mozilla has rolled out comprehensive AI controls in Firefox 148, launching February 24, 2026, allowing users to globally disable all generative AI features across the browser.
The update addresses growing user concerns about AI integration while maintaining optional AI functionality for those who want it.
Firefox 148 AI Control Features
The new AI controls section in desktop browser settings provides centralized management for current and future AI features.
Users can toggle a “Block AI enhancements” switch to disable all AI-powered capabilities globally, preventing pop-ups and feature reminders.
Alternatively, users can granularly manage individual AI features based on personal preferences.
| Feature | Function | Default Status |
|---|---|---|
| Translations | Browse web in preferred language | Optional |
| Alt text in PDFs | Accessibility descriptions for images | Optional |
| AI-enhanced tab grouping | Related tabs and group name suggestions | Optional |
| Link previews | Key points display before opening links | Optional |
| AI chatbot sidebar | Integrated chatbot access (Claude, ChatGPT, Copilot, Gemini, Mistral) | Optional |
Firefox AI controls persist across browser updates, maintaining user preferences without requiring reconfiguration.
The centralized management system allows users to modify settings at any time without affecting other browser functionality.
The implementation ensures that disabled AI features produce no user-facing prompts or notifications.
The global kill switch addresses cybersecurity concerns regarding data transmission to third-party AI services.
Disabling all AI features eliminates potential attack vectors associated with external API calls to generative AI platforms.
Users can prevent inadvertent data exposure to AI service providers through the centralized toggle mechanism.
AI controls will first appear in Firefox Nightly for early testing before the stable Firefox 148 release on February 24, 2026.
Mozilla is actively soliciting community feedback through Mozilla Connect regarding the AI control implementation and future enhancements.
Mozilla emphasizes choice as the primary philosophy behind Firefox AI controls, recognizing divergent user preferences regarding AI integration.
The implementation reflects Mozilla’s commitment to user agency in deciding how AI features interact with their browsing experience.
Whether users embrace or reject AI capabilities, Firefox provides granular control mechanisms to match individual preferences.
