Browsers Add Central AI Opt‑Out

Firefox 156 introduces a single, visible AI controls section in General Settings that lets users block current and future AI features with one toggle and granular per‑feature controls. This moves choice about AI from buried switches to a single control panel and pairs integrated assistants (Smart Window) with advertising‑style sponsored suggestions. — How browsers design and surface AI controls will shape consumer privacy, regulatory claims, platform power, and whether assistants become monetized ad surfaces or privacy‑respecting tools.
