What Does the AI Kill Switch Do in Firefox?
The master switch disables all supported AI functionality in Firefox version 148 and newer, including:
- On-device language translation
- AI-generated alt text in PDF documents
- AI-assisted tab grouping
- Smart link previews
- The optional sidebar chatbot
Note: The chatbot supports multiple providers, including ChatGPT, Claude, Copilot, Gemini, and Mistral. When AI enhancements are blocked, the chatbot interface and related integrations are fully disabled.
How to Disable AI Features in Firefox 148 Using Mozilla’s New AI Controls
- Open Firefox version 148 or newer.
- Click the menu button in the top right corner.
- Select Settings from the menu.
- In the Settings sidebar, scroll until you find the new AI controls section.
- Click AI controls to open the full list of available options.
- Find the toggle labeled Block AI enhancements.
- Turn the toggle on.
Once enabled, Firefox immediately disables all AI features. The browser will no longer display AI prompts, suggestions, notifications, or onboarding messages.
IMPORTANT: Mozilla designed the AI controls so preferences stay set across updates. So after enabling the block, future Firefox updates will not re-enable AI features or introduce new ones without user consent.
For anyone who wants limited AI functionality, you can leave the master toggle off and disable features individually within the same AI controls section. Mozilla designed the system to support both full opt-out and granular customization.
Why Mozilla Added a One-Click AI Off Switch
In late 2025, Mozilla announced plans to evolve Firefox into an AI-powered browser under new CEO Anthony Enzor-DeMeo. The response from longtime Firefox users was overwhelmingly negative. With the bulk of the community voicing concerns about privacy, unnecessary complexity, and a shift away from Mozilla’s traditional focus on user control.
The backlash closely mirrored criticism Microsoft faced when positioning Windows 11 and Edge as AI-centric platforms.
So rather than abandoning AI development, Mozilla committed to making AI optional. The company promised a clear and centralized way to disable AI entirely. Firefox 148 delivers on that promise by introducing what users often refer to as an AI kill switch.
Interestingly, Microsoft has recently stated that they will be scaling back AI features across Windows 11 after a monumental amount of push back against their plan to Agentify Windows with AI.
What About AI in Microsoft Edge?
Microsoft Edge continues to push Copilot deeper into the browser. While some AI-related features can be hidden or partially disabled, Edge does not offer a single off switch. Users must navigate multiple settings pages, including Appearance, Languages, Privacy, and AI-specific sections, to reduce AI behavior. Even then, some Copilot features remain active or reappear after updates.
