On August 18, Mozilla announced an AI window feature update for the Firefox browser. This feature, available as an optional browsing mode, includes a built-in AI assistant. Users can choose whether to enable AI assistance and control the level of interaction. Mozilla emphasizes that the AI window is designed to enhance the browsing experience while prioritizing privacy, avoiding forced intervention in user operations. Users can turn off the feature or adjust the AI model at any time to ensure a personalized experience. Currently, the feature is still under development, and users can register through official channels to participate in testing.
