Firefox Sets Feb. 24 Rollout for AI Master Switch and Per‑Feature Controls

Mozilla says the new AI settings will stick across updates and stop promotional prompts once turned off.

Overview

  • Firefox leadership detailed "AI Controls," a master off switch plus individual toggles for features including translations, PDF alt‑text, AI tab grouping, link previews, and a sidebar chatbot with providers such as Anthropic, ChatGPT, Copilot, Google Gemini, and Le Chat Mistral.
  • The controls are appearing first in Nightly and Beta builds, with general availability planned in Firefox 148 starting February 24, 2026.
  • Ajit Varma said preferences set through AI Controls will persist over future releases, and disabling AI will prevent pop‑ups or notices promoting new AI features.
  • Computer Bild reports the controls can already be surfaced in Firefox 148 Beta by setting the about:config flag browser.preferences.aiControls to true.
  • Mozilla framed the move as a response to significant user pushback, as rival strategies diverge with Vivaldi publicly rejecting more AI tools and Waterfox remaining AI‑free by design.
