GoKawiilMozilla adds AI form-fill and page-watching to Firefox's Smart Window beta
Mozilla is rolling out two new capabilities to Firefox's Smart Window AI browsing beta: a tool that auto-fills web forms using data pulled from a user's open tabs, and a 'watch' feature that monitors specified webpages for changes like sales or job postings. The form-fill feature works on text fields with four or more entries and sends source-page data to Google's Gemini 3.1 Flash Lite model, while the watch feature checks pages daily or weekly and notifies users via the Tasks button or desktop alerts. Both features launch first on desktop in the US and Canada, with wider rollout planned for coming months.
GoKawiil's interpretation of the reporting above, not reported fact.
The update pushes Firefox further into agentic, AI-assisted browsing, competing with similar features from Chrome and other browsers racing to make AI an embedded daily utility rather than a separate chatbot. Sending open-tab data to a third-party model like Gemini raises privacy considerations that users may need to weigh against the convenience gained. The feature's current limits — no dropdown or PDF support, and watch tasks that lapse after 90 days — suggest Mozilla is still treating this as an experimental, iterative beta rather than a finished product.
- Smart Window can now auto-fill web forms using data from a user's open browser tabs.
- A new '/watch' command lets users monitor webpages for updates like sales or job listings, checked daily or weekly.
- Features are in beta on US/Canada desktop Firefox, and form data is processed via Google's Gemini 3.1 Flash Lite.
