In a user-centric move amid growing concerns over AI integration in browsers, Mozilla has announced a major update to Firefox that gives users full control over generative AI features. Starting with Firefox 148 (rolling out February 24, 2026), a new AI Controls section appears in the desktop browser settings. It features a single master toggle called “Block AI enhancements” that instantly disables all current and future generative AI tools in one click.
This change directly responds to user feedback about unwanted AI features, pop-ups, and prompts. Mozilla emphasizes privacy, choice, and transparency—allowing users to browse without AI while continuing development for those who want it.
Key Details of the New AI Controls in Firefox
- Location: Settings > AI Controls (new dedicated section in desktop Firefox).
- Main Toggle: “Block AI enhancements” – When enabled:
- Disables all current and future generative AI features.
- Prevents pop-ups, notifications, reminders, or suggestions about existing/upcoming AI tools.
- Settings persist across updates—no need to reconfigure after upgrades.
- Granular Management: Users who want selective AI can toggle individual features on/off instead of the global block.
Current AI Features Affected (Manageable Individually or via Global Toggle):
- Translations — AI-powered real-time page translation for browsing in your preferred language.
- Alt Text in PDFs — Generates accessibility descriptions for images in PDF documents.
- AI-Enhanced Tab Grouping — Suggests related tabs and automatic group names for better organization.
- Link Previews — Displays AI-generated “key points” or summaries before clicking links.
- Sidebar AI Chatbots — Access to third-party models like Anthropic Claude, ChatGPT, Microsoft Copilot, Google Gemini, and Le Chat Mistral directly in the Firefox sidebar.
Enabling the global “Block AI enhancements” toggle removes all of these, plus any future generative AI additions Mozilla may introduce.
Why This Matters: User Choice in the AI Browser Era
Mozilla’s approach contrasts with competitors like Google Chrome, Microsoft Edge, and others that deeply embed AI without easy full opt-outs. By adding this AI kill switch, Firefox reinforces its commitment to:
- Privacy-focused browsing
- User empowerment and transparency
- Optional AI (not forced integration)
The update builds on Mozilla’s earlier promises (from late 2025 leadership changes) to keep AI as a choice, not a default intrusion. It’s especially welcome for privacy advocates, developers, and users wary of data usage, hallucinations, or performance overhead from on-device or cloud AI.
How to Access AI Controls (Once Firefox 148 Releases)
- Update to Firefox 148 (auto-updates or manual download from mozilla.org).
- Go to about:preferences (or Menu > Settings).
- Navigate to the new AI Controls section.
- Toggle “Block AI enhancements” on for complete disablement.
- (Optional) Review and customize individual features below.
Note: These controls apply to desktop Firefox; mobile and other platforms may follow in future releases. Traditional (non-generative) ML features remain unaffected unless specified.
