Overview
- Mozilla began rolling out Smart Window as an opt-in beta in the U.S. and Canada on Tuesday, August 18, 2026, and users can enable or disable the feature and delete stored “memories” at any time.
- The initial feature set added on launch lets Smart Window pull current web information with source links through a paid partnership with Exa, automatically suggest tab groups, and show visual previews from browsing history.
- Users can select which AI model powers Smart Window by choosing cloud-hosted options or running a local model, and Mozilla says third-party inference runs under zero-data-retention contracts to limit data use.
- Mozilla is paying Exa for the web-search capability so Smart Window does not immediately diversify Mozilla’s revenue, and the company has not given a firm date for exiting beta.
- The update brings Firefox into broader industry experiments with AI in browsers by letting people ask about open tabs and past sessions, and the outcome will hinge on user adoption, privacy audits, and future choices about monetization.
