Overview
- An AI controls panel debuts in Firefox 148 with a “Block AI enhancements” toggle that can disable current and future generative features in one step.
- The rollout starts in Firefox Nightly now and expands to all desktop users on February 24, 2026.
- When turned on, the master toggle also suppresses prompts about AI features and preserves those preferences across browser updates.
- Users can manage five tools individually: translations, PDF image alt text, AI tab grouping suggestions, link previews with key points, and a sidebar chatbot.
- The sidebar supports multiple third‑party chatbots, including Anthropic Claude, ChatGPT, Microsoft Copilot, Google Gemini, and Le Chat Mistral, and Mozilla is gathering feedback through Mozilla Connect with controls reflecting prior user choices and the master toggle set off by default.
