GoKawiilMozilla adds AI form-filling and website monitoring to Firefox's Smart Window
Mozilla has added two new features to Smart Window, its opt-in AI browsing tool in Firefox: AI-powered form filling and website monitoring. The form-filling tool uses Google's Gemini 3.1 Flash Lite model to pull context from other open tabs—such as a portfolio or professional profile—to answer form fields beyond basic autofill data like name and address.
GoKawiil's interpretation of the reporting above, not reported fact.
Sending tab content to an external AI model to fill in forms raises questions about how much browsing data users are comfortable sharing, even in an opt-in feature. The move also shows Mozilla continuing to build out AI assistant capabilities directly into Firefox, following earlier additions like AI search and natural-language history search, as it competes with AI-infused browsers from other companies.
- Smart Window now offers AI form-filling using Gemini 3.1 Flash Lite to pull data from other open tabs.
- A new website monitoring feature is also rolling out, described as working similarly to Safari's version.
- The features build on Smart Window's earlier additions like AI search, tab grouping, and natural-language history search.
