Mozilla is introducing an AI-powered feature called Smart Window to Firefox, which offers augmented browser windows and tabs. This new functionality allows users to ask questions and receive assistance on open tabs and internet content through an integrated AI chat interface. Crucially, the feature is opt-in, providing users with control over their browsing experience. Those who choose to enable Smart Window can interact with it similarly to other AI chat tools, with responses appearing in a side panel. The AI can answer questions about currently open tabs by referencing browsing history, or utilize Exa's search engine for broader internet queries. Exa's search engine powers internet-based questions by using custom AI models and extensive web crawling. Mozilla and Exa emphasize that neither company retains data from these AI-powered searches unless users opt into specific training programs. Users can manage their AI data, delete "memories," and disable or toggle off Smart Window at any time. Mozilla aims to provide choice, catering to both AI enthusiasts and those who prefer traditional browsing. The company is also exploring future AI integrations that could help configure Firefox settings or create extensions. While not the first attempt at an AI-centric browser, Mozilla leverages its extensive browser development experience. The company's revenue is not immediately diversified by this feature, as Mozilla pays Exa, but they believe long-term monetization opportunities will arise from user value.
