Firefox’s Smart Window adds AI form-filling from open tabs and webpage 'watch' feature
Mozilla updated Firefox’s Smart Window with two features: an AI-assisted form-filling option that can pull text from your open tabs (you choose which tabs to use) and a '/watch' webpage-monitoring task that checks specified pages for changes on a daily or weekly basis while the browser is open. Generated suggestions are produced by Google’s Gemini 3.1 Flash Lite model; the features currently support text fields (dropdowns and PDFs are planned) and are rolling out to the Smart Window beta in the US and Canada.
