Mozilla has introduced AI Window, its next major AI-driven feature for Firefox, emphasizing the company’s long-standing principles of choice, transparency, and openness. Unlike other browsers pushing tightly integrated AI ecosystems, Mozilla says Firefox will never require users to adopt AI nor lock them into a single provider.

AI Window: An Optional, Independent AI Panel in Firefox

AI Window is a new intelligent sidebar-like panel built directly into Firefox. Users can chat with an AI assistant, access tools, summarize pages, or perform tasks – all without leaving the browsing experience.

True to Mozilla’s approach, AI Window is:

• Fully optional and user-controlled
• Compatible with Private Window mode
• Toggleable at any time
• Designed to preserve user agency

Mozilla describes it as a natural extension of its mission to give users more ways to interact with the web – not fewer – while keeping control firmly in their hands.

A Flexible, Open AI Approach – Not Vendor Lock-In

Instead of forcing AI into every corner of Firefox or tying users to one ecosystem, Mozilla wants to support:

• Users who rely heavily on AI
• Those who use it occasionally
• And those still experimenting

Firefox’s strategy is centered on flexibility, ensuring people can choose if, when, and how they want AI involved in their workflow.

With AI becoming a primary interface for accessing web information, Mozilla argues that independent, open-source players are needed to:

• Keep AI tools transparent and accountable
• Maintain user agency and privacy
• Prevent the web from being boxed into closed conversational systems

Mozilla sees AI Window as a step toward ensuring the internet remains open, accessible, and user-first.

Firefox’s Earlier AI Features

AI Window builds on the optional AI features Firefox introduced earlier this year, including:

• Desktop AI chatbot sidebar
• Shake to Summarize on iOS
• Automatic alt-text generation
• On-device translation
• Smart link previews
• Tab-group naming suggestions

Firefox also supports multiple AI providers like Anthropic Claude, ChatGPT, Google Gemini, Microsoft Copilot, and Le Chat Mistral, allowing users to choose their preferred assistant. Privacy remains a priority; many tasks run on-device whenever possible.

Availability

• AI Window is fully opt-in
