Firefox updates Smart Window: A new in-browser AI assistant that can keep up with you

Mozilla's beta AI feature Smart Window now helps Firefox users track tabs, summarize research and pick up where they left off. It uses your own browsing context privately, so you don't lose the plot after a lunch break.

Mozilla pushed an update to Firefox today aimed at a very specific kind of chaos: the twelve-tabs-deep research spiral that happens when you're trying to buy a computer part, or really anything with too many options. The feature is called Smart Window, and it's still in beta, but it's clearly meant to fix the moment where you walk away for lunch and come back to a browser full of shops, review sites, and forgotten context.
Smart Window isn't brand new. It grew out of AI Window, a concept Mozilla floated last November to test how a privacy-first AI assistant might live inside the browsing experience. Since then, the company has spent a few months building it out with community testers, and today's update adds the ability to check answers without losing your place while you research, compare, and jump between tabs.
Ajit Varma, Mozilla's Head of Firefox, framed it as putting the browser's existing knowledge to work. The browser already sees your open tabs, your visited pages, the things you stumbled across along the way — Smart Window just tries to make that pile of context actually useful, he said, while leaving the user in control.
The practical hook is search. Mozilla partnered with Exa Labs Inc., an AI search company, so Smart Window can surface relevant results directly in a chat-style interface without dragging you off to a new tab. It also pulls up relevant open tabs when you ask it questions, so if you can't remember which review site had the best price, or what you were even comparing three months ago, it can point you back to it instead of forcing you into a fresh Google search with the wrong keywords.
Mozilla says the feature is far from finished. Coming updates should let Smart Window learn from a user's recent browsing journeys, stitching together related tabs and history so people get a working starting point rather than a blank chat box every time. Eventually it will suggest likely questions on its own, cutting down on repetitive typing. For now, Smart Window stays in beta, and it's only available in English to users in the United States and Canada.
My take — AI-written commentary, not fact-checked reporting
Tucking an AI assistant into the browser itself, rather than bolting on yet another app, is the right instinct — the browser genuinely does hold all that scattered research context that gets lost the moment you close a tab. The real test is whether Mozilla can make
