Firefox’s Smart Window promises a better AI browser

Details

Starting today, Firefox's Smart Window browsing mode adds live web search via a new Exa partnership, with citations shown inline in AI chat responses. Smart Window can also auto-suggest tab groups, find and close duplicate tabs, and display visual page previews from browsing history when searched using natural language — all new in this update.\n\nMozilla's head of Firefox, Ajit Varma, described the approach as 'agnostic': features are opt-in, users choose which AI model powers Smart Window (including Google's Gemini 3.1), and a new AI Controls section in Firefox settings lets anyone toggle all AI features off collectively or select them individually. Mozilla is explicitly not trying to route users toward more LLM queries — Smart Window organizes what you've already browsed rather than generating new content.\n\nBeta users reported Smart Window helped them maintain their train of thought across browsing sessions. A live demo showed the AI sorting through selected links to surface 'running shoes I looked at last week' with images pulled from the original pages. Future updates will add Chrome-like browsing journey surfacing and AI-powered form autofill.\n\nThe positioning differs meaningfully from competitors: while other AI browsers direct users toward more chat interaction, Firefox treats AI as a behind-the-scenes organizer of existing browsing. Smart Window remains in opt-in beta with no date set for general availability.
