Summary
Mozilla is testing Smart Window, a separate, opt-in Firefox window for chatting with an AI assistant while you browse. You pick the model and can turn the whole thing off; Firefox's one-click AI kill switch arrived earlier this year. It extends Mozilla's existing sidebar chatbot and leans on "user choice" as the pitch against browsers built by AI companies. The window sits alongside Firefox's Classic and Private modes.
