Firefox Adds One-Click Switch to Block All AI Features, Rolling Out Feb. 24

Mozilla positions the control as a user-choice safeguard in a market where rival browsers lack a single off switch.

Overview

  • Mozilla confirmed a new AI controls section in Firefox settings, debuting in version 148 on February 24 after testing in Nightly builds.
  • The global Block AI enhancements toggle disables existing and upcoming generative features and suppresses pop-ups promoting them.
  • Users can manage individual tools for translations, alt text in PDFs, AI tab grouping, link previews, and a sidebar chatbot that supports Claude, ChatGPT, Copilot, Gemini, and Le Chat Mistral.
  • The toggle will be off by default, with controls reflecting prior choices and preferences persisting across updates.
  • Mozilla says the move follows user feedback and leadership pledges to keep AI optional, and it is inviting early comments through Mozilla Connect.
