Firefox Will Give Users an AI Kill Switch for Better Privacy

**Executive summary:** Mozilla will release Firefox 148 on 24 February 2026, introducing a dedicated AI controls section that includes a global "Block AI enhancements" toggle to opt out of current and future AI features; users can also customize which AI capabilities remain enabled (chatbot sidebar, translations, link previews, AI tab grouping, PDF alt-text). The features are being trialed in Firefox Nightly and Mozilla is soliciting user feedback via Mozilla Connect to refine preferences preservation and balance privacy with functionality.
