Overview
- Mozilla began offering Smart Window as an English-language opt-in beta for U.S. and Canadian Firefox users through a waitlist, with the company announcing the update on Tuesday, August 18, 2026.
- A new partnership with Exa lets Smart Window pull current web information into AI chat replies and display source links inside the browser without sending users to a separate search page.
- Smart Window now supports natural-language search of browsing history, visual page previews to identify past pages, automatic tab grouping, and duplicate-tab detection to help users resume and organize work.
- Users can choose which AI model powers Smart Window, including hosted third-party models or local models, and Mozilla and Exa say searches operate under zero-data-retention terms while Mozilla will not store chats without user permission.
- Mozilla frames the rollout as a privacy-first, choice-driven alternative to vendor-locked AI browsers and says it will add features like surfaced browsing journeys and AI form autofill in future updates but has not set a date to exit beta.
