Firefox's Smart Window AI browser enhances browsing with Exa and natural language

Mozilla’s Firefox Smart Window AI browsing mode, a user-first and privacy-focused enhancement, has rolled out new features to help users better track and utilize their browsing history. Announced today, the update integrates with Exa to allow AI chats to pull real-time web information and cite sources directly within chat responses. This means users can now ask Smart Window to recall specific content they viewed earlier—like “running shoes I looked at last week”—and receive visual previews pulled from previously visited pages. Additionally, Smart Window automatically suggests and organizes tab groups, even identifying and closing duplicate tabs to streamline workflows.

Under the hood, Smart Window remains an opt-in beta feature, with Mozilla taking a user-centric approach by allowing users to toggle AI features on or off in a new AI Controls section. Users can choose from multiple AI models, including Google’s Gemini 3.1 Flash Lite, OpenAI’s oss-gpt-120b, and Alibaba’s Qwen3-235B-A22B-Instruct-2507, or run local models for digital sovereignty. Mozilla emphasizes privacy, ensuring third-party AI providers operate under zero-data-retention contracts and that user prompts and chats aren’t stored or used for training or advertising—reinforcing its stance as a neutral, user-first browser.
