Mozilla unveils AI Window for user-controlled browsing in Firefox


Mozilla has previewed AI Window, its next major AI feature in Firefox, built around the same principles that guide its broader AI work: choice, transparency and openness.

The company says users will never be required to use AI or be limited to a single ecosystem, and Firefox will continue offering flexible experiences that let people decide how much AI they want — or whether they want it at all.

AI Window: a new user-controlled space inside Firefox

AI Window is an upcoming intelligent panel within Firefox that lets users chat with an AI assistant and access helpful tools while browsing, entirely on their terms. It sits alongside the classic Firefox interface, including Private Window mode, and can be turned on or off at any time. Mozilla positions AI Window as an extension of its effort to give users new ways to interact with the web while keeping control firmly in their hands.

Designed around flexibility, not lock-in

Mozilla says it aims to build a browser that adapts to different usage patterns. Some people use AI frequently, others only occasionally, and many are still exploring what AI can offer. Firefox’s approach avoids forcing AI into the browsing experience or tying users to proprietary environments. Instead, the focus is on flexibility and transparent decision-making.

Why Mozilla is investing in AI

As AI becomes a common interface for navigating the web, Mozilla highlights the importance of keeping these tools open, accountable and aligned with user agency. The company believes an independent browser has a role in shaping how AI integrates into the web — encouraging discovery rather than keeping people within closed conversational systems. Mozilla sees this work as essential to supporting a free and accessible web.

Earlier Firefox AI features

Earlier this year, Firefox introduced several optional AI features such as the desktop chatbot sidebar, Shake to Summarize on iOS, automatic alt text generation, on-device translation, tab-group naming suggestions and link previews. These capabilities are processed locally where possible to maintain privacy.

Firefox also supports multiple chatbot providers — including Anthropic Claude, ChatGPT, Google Gemini, Microsoft Copilot and Le Chat Mistral — for tasks like summarizing pages, drafting content or asking questions directly from the sidebar.
