What changes in the browser
Mozilla announced on October 27 an expansion of the capabilities of 'Smart Window,' Firefox's AI-assisted browsing feature. According to the source, the update introduces two distinct tools: automatic form filling and monitoring of changes to web pages. Both are currently reserved for a subset of users trying the desktop beta version.
The first new feature concerns online forms. In addition to traditional data such as name, address, and contact details, the system can draw on the content of other open tabs to reconstruct information such as professional experience, for example from a portfolio or work profile. It can also draft answers to open-ended questions, such as 'describe a time when...,' based on the materials available in the tabs.
Dependence on the cloud and models
AI form filling involves transferring some data to the cloud. Mozilla indicates the use of Google's Gemini 3.1 Flash Lite model to analyze form fields and extract information from selected tabs. However, the company specifies that Firefox's ordinary autofill remains available without AI, merely entering saved data such as name and address.
The second tool, page monitoring, works through a command typed into the Smart Window chat. Users can ask the browser to track changes such as price drops, product restocks, or new job listings. Alerts can be viewed via a button in the toolbar or through desktop notifications. In this case, change detection is handled by the Qwen model.
Limits and markets
The source material details some operational constraints. Checks can run daily or weekly; each task can cover at most five pages, and users can keep up to 15 tasks active simultaneously. If no matches occur for 60 days, the task is automatically suspended, while after 90 days without changes monitoring stops entirely.
Availability is currently limited: the two features are accessible in the Smart Window desktop beta only for English-speaking users in the United States and Canada. Mozilla stated its intention to extend the features to other markets in the coming months, without providing dates or lists of countries.
To be verified
Some elements remain uncovered by the information released. It is not known what data protection measures accompany the transfer to the cloud of information extracted from tabs, nor how users can control or revoke access to the content. The timeline for extending to other markets, any availability in Italian, and the pricing terms of the features are not specified. The news is based on Mozilla's announcement as reported by the source and not on independent verification of how the tools work.
