Firefox Smart Window adds AI form filling and web page monitoring features
Mozilla has added a form filling feature to Smart Window, Firefox's AI browsing experience. It can extract information from open tabs to generate filling suggestions, and the data will be shared with Google's Gemini 3.1 Flash Lite model. Users can also type /watch in the Smart Window chat to have the browser monitor specified web pages daily or weekly for changes such as promotions and job postings. It only checks while the browser is open, pauses after 60 days without changes, and stops after 90 days. Both features have launched in the Smart Window beta on desktop in the United States and Canada, and will roll out in other countries in the coming months.

Mozilla is updating Smart Window — Firefox’s AI-powered browsing experience — with a new feature that can help you fill out online forms based on your open tabs. As an example, Mozilla says Smart Window can pull information from your online portfolio or LinkedIn page to paste your work history into a job application.
You can try out this feature by clicking into a form with at least four text fields. From there, you’ll see an option to “Fill from sources,” which will show all of the tabs Firefox will draw from. You can then select or deselect tabs that you want Firefox to use, and the browser will generate suggestions based on the information in them. This feature currently supports text fields on web forms, but Mozilla is working to add support for dropdown menus and PDFs. Mozilla notes that data from your source pages is shared with Google’s Gemini 3.1 Flash Lite, the AI model that generates the text suggestions.
Along with this update, you can now ask Firefox’s Smart Window to watch a certain webpage for sales, new job listings, and other updates. You can set up a task by typing “/watch” in the Smart Window chat, describing what you’re looking for, and adding the webpages you want to watch. Firefox can then check for updates on a daily or weekly basis, but only when the browser is open.
When Firefox detects the change you’re looking for, it will send you a notification through the Tasks button on the toolbar, or on your desktop (if you have desktop notifications enabled). Firefox will pause watching for updates if it doesn’t detect a change after 60 days, before stopping them completely after 90 days.
These two features are rolling out to the Smart Window beta on desktop in the US and Canada. They’ll be available in other countries in the “coming months.”
