Firefox Smart Window gains AI search, tab grouping and more

Mozilla first introduced Smart Window a few months ago as an optional, separate window in Firefox where users can interact with an AI assistant of their choice while browsing. The company said it offered tools for summarizing, comparing tabs, organizing information, and asking questions without leaving the browsing flow. Since then, Mozilla has incorporated user feedback into the feature.

The new tab grouping suggests groups for related tabs, which Mozilla says will help users when researching a topic or planning an event. Duplicate detection allows users to spot and close duplicate tabs with a single click. A newly announced partnership with Exa, an AI-focused search and web retrieval company, enables Smart Window to retrieve current web information and show the sources behind its response without taking users to a separate search results page.

Smart Window also accepts natural-language prompts such as "running shows I looked at last week" and will show visual previews of pages from the user's browsing history, making it easier to identify the desired page among similar results without opening each one.

Mozilla also detailed what is coming next for Smart Window. The company plans to surface recent browsing journeys, combine related tabs and history, and use relevant information to help fill out online forms, sparing users from re-entering details. Mozilla emphasized that users will keep control over what Smart Window can access, including which tabs they choose to share.

Smart Window is currently available in English as a beta for Firefox users in the U.S. and Canada.
