Overview
- A new AI Controls section centralizes settings, including a "Block AI enhancements" master toggle to disable current and future generative features and suppress prompts.
- Nightly testers can try the controls now, with Firefox 148 bringing them to all desktop users on February 24.
- Users can manage features individually: translations, PDF alt text, AI tab grouping, link previews, and a sidebar chatbot supporting Claude, ChatGPT, Copilot, Gemini and Le Chat Mistral.
- Preferences will persist across updates, the master toggle is off by default, and the panel reflects past choices as enabled, blocked or available.
- Mozilla leaders cast the move as empowering choice, while analysts note it remains an opt-out model; reporting also highlights Mozilla’s parallel push for AI transparency and planned deployment of roughly $1.4 billion in reserves.
