Firefox Smart Window’s desktop beta is adding two capabilities: form suggestions based on chosen tabs and webpage monitoring. Mozilla says the rollout is under way in the US and Canada. The features are expected in other countries in the coming months.
How does form filling use open tabs?
A user opens a web form with at least four text fields to see the “Fill from sources” option. That option lists the tabs Firefox may consult, and the user can choose which ones to include. Firefox then produces suggested text using information from the selected pages.
Mozilla’s example is a job application that could draw work history from an online portfolio or LinkedIn page. The feature currently handles text fields on web forms. Mozilla is working on adding support for dropdown menus and PDFs, but the supplied account does not give a release date for those additions.
Which model receives page information?
The source material says that data from selected pages is shared with Gemini 3.1 Flash Lite, which generates the text suggestions. It does not explain how long that data is kept or give details about controls for reviewing or deleting it. Those details are not specified in the feature description provided.
How can a page be monitored?
In Smart Window chat, a user types “/watch”, describes the update they want to find, and adds the webpages to check. This creates a task for checking those pages for changes such as sales or new job listings. Firefox performs checks daily or weekly, and only while the browser is open.
Where do change notifications appear?
If Firefox finds the requested change, it can send a notification through the Tasks button on the toolbar. Desktop notifications are another option when enabled. The account does not explain how the browser decides whether a page change matches the user’s description.
When does monitoring pause or stop?
Firefox pauses monitoring if it finds no change for 60 days, then stops it completely after 90 days. These limits describe what happens to a task without a detected change; the source does not state whether a user can adjust them. The browser also needs to be open for its scheduled checks to run.
For founders and technology teams, the update shows how browser features can draw on information across several open pages. Users control which tabs supply form suggestions, while monitoring depends on an open browser and a defined task. Mozilla says rollout beyond the US and Canada is expected in the coming months, but gives no dates for individual countries or for expanded form support.
