Mistral and Mozilla announced a partnership to power Firefox Smart Window, Mozilla's AI browsing assistant, with Mistral models. The service will be available to users in France and North America, with the United Kingdom and Germany expected to follow later in 2026. Mistral's models are fine-tuned on regional languages and dialects, and conversations are not saved on Mozilla's servers by default.

## Evidence

Verbatim from https://mistral.ai/news/mistral-x-mozilla/:

> Firefox Smart Window (beta), Mozilla's AI browsing assistant, is now powered by Mistral models. Smart Window helps you make sense of complex searches, remember something important you clicked away from and source information important to you based on your browser tabs. Mistral will help power Smart Window for users in France and North America, with the United Kingdom and Germany expected to follow later this year.
