   Firefox tests AI Smart Window feature that can automatically fill out web forms

   Mozilla demonstrated Firefox's Smart Window feature, which runs as a sidebar and lets users use natural language to ask it to fill out web forms such as job applications, service bookings, or online registrations. The feature analyzes form fields on the page, extracts names, contact information, and work experience from materials such as resumes, and fills them into the corresponding fields. Before submission, it shows the user the content to be submitted for review and modification. Mozilla says its positioning is as an intelligent assistant that can understand and operate web content, rather than a mere chatbot, and emphasizes that users can control the scope of information the AI can access. The feature is currently still in testing, and no timeline has been announced for making it available to all Firefox users.

   Firefox's AI-powered Smart Window adds form autofill and web monitoring

   Mozilla has added two features to Smart Window, Firefox's AI browsing experience: AI form autofill and web monitoring, now available to desktop beta users. Form filling uses Google Gemini 3.1 Flash Lite to extract information from other tabs and generate answers, while web monitoring uses Qwen to detect changes in price, stock, or job listings, with up to 15 tasks and 5 web pages per task. Both features are currently limited to English-speaking users in the United States and Canada.

   Mozilla adds AI form filling and page monitoring to Firefox Smart Window

   On October 27, 2026, Mozilla announced that the beta version of Firefox's Smart Window adds two capabilities: extracting information from user-selected tabs to help fill out online forms, and monitoring web page changes based on user descriptions. Form filling uses Gemini 3.1 Flash Lite to identify fields and extract information, while page monitoring uses the Qwen model, even if another model is selected in the Smart Window settings; saved autofill data remains local and is not sent to the model. Both features are currently available to English-language desktop beta users in the United States and Canada, and page monitoring tracks up to 5 pages per task and retains up to 15 active tasks.

   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.
