Mistral to Power Mozilla Firefox's Smart Window AI Assistant

Mozilla and Mistral partnered so Mistral's models power the Firefox Smart Window beta AI browsing assistant, launching in France and North America with zero data retention; the UK and Germany are expected later this year.

Mozilla's Firefox Smart Window (beta), an AI browsing assistant for complex searches, content recall, and tab summarization, is now powered by Mistral's models. The feature launched first in France and North America, with the UK and Germany expected to follow later this year. Conversations are not saved on Mozilla's servers by default, and Mistral agreed to zero data retention. Both companies frame the partnership as advancing open-source, privacy-first, and regionally fine-tuned AI, with models trained on regional languages, dialects, and cultural context. According to The Decoder, the deal also marks Mistral's push beyond business customers to end users.
