Firefox's Smart Window Adds AI-Powered Form Filling and Page Monitoring
Form filling uses open tabs, while monitoring works only when the browser is open and is currently available in the U.S. and Canada

Mozilla has updated Smart Window, an AI feature in Firefox, with the ability to transfer data from open tabs into web forms. After selecting the 'Fill from sources' option, the browser displays available pages and suggests options for text fields. Currently, only text fields are supported, with plans to add support for dropdown menus and PDF files. Data from the pages is sent to Google Gemini 3.1 Flash Lite, which generates suggestions.
Smart Window has also introduced the '/watch' command for tracking changes on selected websites. Users can set up daily or weekly checks for pages, such as discount announcements or new job postings. If changes are detected, Firefox will send a notification via the Tasks button or to the desktop if notifications are enabled. If no changes occur within 60 days, monitoring will be paused, and it will be discontinued entirely after 90 days.
