Mistral AI to Power Firefox Smart Window as Mozilla Extends Its AI Push to France and North America
Mozilla announced on September 16, 2026 that its Firefox Smart Window AI assistant is now powered by Mistral models, launching in beta across France and North America with the UK and Germany to follow later in 2026. The partnership pairs two open source advocates, with Mozilla citing open distribution and user control while Mistral gains consumer reach beyond its enterprise base. Mozilla says conversations are not saved on its servers by default and partners agree to zero data retention.
