The new feature: filling in forms from tabs
Mozilla updates Smart Window, Firefox's AI-based browsing mode, with a feature that helps fill in online forms by drawing on the tabs open in the browser. The Verge reports. According to Mozilla's description, the feature can, for example, retrieve information from an online portfolio or a LinkedIn page to enter one's work experience in a job application.
The option is activated by clicking in a form with at least four text fields: the item Fill from sources appears, showing the tabs from which Firefox intends to take the data. The user can select or deselect the sources, and the browser generates suggestions based on the information they contain. At present the feature covers only text fields, while Mozilla says it is working on support for drop-down menus and PDFs.
The model's role and current limitations
Mozilla specifies that data from the source pages is shared with Google's Gemini 3.1 Flash Lite, the model that produces the suggested texts. This is a relevant detail for those assessing privacy: the filling does not take place entirely locally but goes through a third-party model.
Aspects not covered by the material remain to be clarified, such as consent procedures and guarantees on data processing. Transparency about the model provider is confirmed, but there are no indications of how personal information extracted from the tabs is handled.
Web page monitoring
The second update allows users to ask Smart Window to monitor a web page for offers, new job listings and other updates. The user types /watch in the chat, describes what they are looking for and indicates the pages to watch. Firefox checks for updates daily or weekly, but only when the browser is open.
When it detects the desired change, the browser sends a notification via the Tasks button on the toolbar or on the desktop, if notifications are enabled. Monitoring is paused if no change is detected after 60 days and stops entirely after 90 days.
Availability and open questions
The two features are rolling out in the Smart Window beta on desktop in the United States and Canada; according to Mozilla, they will arrive in other countries in the coming months. The rollout is therefore gradual and geographically limited.
The picture that emerges is an expansion of Smart Window's capabilities, moving from consulting pages to actively reading them: filling in a form or monitoring a site on the user's behalf. These are potentially useful features, but they raise questions about data control and the reliability of suggestions. The material does not indicate how the user can correct or verify the generated information, nor does it provide data on accuracy. These elements remain to be verified.
