Firefox, the independent web browser from Mozilla Corporation, has unveiled its next major feature: AI Window. This new mode will soon sit alongside the Classic and Private windows in Firefox, offering a fully opt-in space where users can interact with an AI assistant while browsing, on their terms. One user described it as “my web, my way, but smarter.”
Unlike many browsers that tightly couple users to one AI ecosystem, AI Window empowers you to choose the model, switch it off entirely, or restrict its use. Meaning you decide when, how and whether AI becomes part of your browsing. That’s the philosophy Mozilla calls “building AI the Firefox way.”
In recent years many major browsers have scrambled to embed AI assistants. Chrome now layers Gemini features, Edge offers Copilot mode and niche challengers have built entire browsers around chatbots. In contrast, Mozilla is placing its strategy on three principles: openness, model-choice and user agency.
Mozilla’s emphasis on agency comes at a moment when AI regulation, browser dominance and data control are under global scrutiny.
Browsers are increasingly becoming major battlegrounds for AI-driven user interaction. With AI Window, Firefox is attempting not just to add an assistant, but to redefine how AI becomes part of the web. This approach advances several broader trends:
Firefox’s new AI Window introduces an independent browsing mode that lets users open a dedicated space for AI-powered tasks, where they can ask for contextual help, summarise complex content or draft text without leaving the page. Unlike other browsers that lock users into a single AI provider, Mozilla plans to offer model selection so people know exactly which system is handling their queries.
Importantly, the feature is entirely opt-in: nothing changes for users who prefer the classic or private browsing experience, and AI tools only appear when the AI Window is opened. True to Mozilla’s open-source principles, the feature is being built transparently, with developers and users encouraged to share feedback through Mozilla Connect and test early preview builds. While Mozilla hasn’t confirmed a full global rollout timeline, it has launched a waitlist for those who want early access and the chance to shape the feature before public release.
