Mistral AI says it has teamed with Mozilla to put its models behind AI browsing features in Firefox, with the Smart Window beta now running on Mistral technology. The beta is live in France and North America, and Mistral's announcement says the UK and Germany are expected later this year. Neither company disclosed pricing, model names or versions, and there is no word on availability beyond those regions.
Smart Window is built to help with harder searches, recalling what a user has already looked at and pulling sources from open tabs. The two companies frame the tie-up as a shared bet on open source, and the announcement says Mozilla does not keep those conversations on its servers by default, with partners such as Mistral agreeing to zero data retention.

The deal marks a shift in who Mistral sells to. The company has traditionally focused on enterprise customers, and this partnership pushes it toward consumers worldwide. It also follows Mistral's August announcement of in-region inference, open models and new European infrastructure, part of a roadmap toward sovereign AI capacity.
Mozilla's side of the bargain is its long-running campaign for an open web, which it has argued for over two decades. Mistral, for its part, has shipped open weight frontier models since its first release. Anthony Enzor-DeMeo, CEO of Mozilla Corporation, said the arrangement is about more than distribution: "This isn't just a product partnership. A browser shouldn’t be a one-way funnel. It should preserve what made the internet powerful to begin with: the freedom to explore, discover different ideas and tech, and decide for ourselves where to go next."
What the announcement leaves open is how the economics work. With no price attached to the partnership and no model versions named, readers cannot yet tell which Mistral systems are handling their queries or what Mozilla pays for them. The UK and German launches are also undated beyond a rough window of later this year.
For Firefox users in the two launch regions, the practical change is that the Smart Window beta now answers complex searches and traces them back to the tabs they came from, without those conversations being kept on Mozilla's servers by default. Whether that privacy arrangement holds as the feature expands to more countries is not addressed in the announcement.
