Mistral Takes Over Firefox Smart Window and Extends It to France Under Zero Data Retention

Mozilla's Firefox Smart Window beta is now powered by Mistral models, and Firefox 155 rolls the feature out in France in French, its first market beyond North America, with the UK and Germany expected later this year. Conversations are not saved on Mozilla's servers by default and Mistral agreed to zero data retention as a condition of the partnership. This is the first browser-scale distribution win for a European model provider on an explicitly privacy-contractual basis, which matters more as a procurement template than as a product launch.
