Firefox's AI assistant now runs on Mistral
Mozilla's Firefox Smart Window (beta), an AI assistant that helps with searches and remembers what you browsed, is now powered by Mistral. It starts in France and North America, with the UK and Germany later this year. Both companies pitch it on privacy and on models tuned to local languages.
