Mozilla fires up the browser wars with its new Firefox AI browser feature. On November 14, 2025, the company unveiled “AI Window,” an optional tool that personalises browsing with AI smarts. Unlike chat-locked rivals, Firefox positions AI as a web guide, not a cage. This opt-in upgrade aims to snag market share from Google Chrome’s 69% grip. As Perplexity’s Comet and OpenAI’s Atlas push agentic AI, Firefox’s move, its third AI perk, leverages the Gecko engine for a fresh edge. Users join a waitlist for early access, choosing models and toggling freely. So, here are all the details about it.
Inside Firefox AI Browser’s AI Window
Mozilla builds AI Window “in the open,” letting users chat with an assistant mid-browse. It enhances discovery without trapping you in loops. Toggle it off anytime for classic Firefox vibes.

Key features of Firefox AI Browser:
- Personalized Chats: AI helps navigate sites, summarize content, and suggest links.
- Model Choice: Pick your preferred AI engine for tailored responses.
- Opt-In Control: Activate via waitlist; disable completely if desired.
- Privacy Focus: Guides users outward to the web, respecting Mozilla’s ethos.
This joins Firefox’s AI lineup: a desktop sidebar chatbot and iOS “Shake to Summarize” for quick page overviews. Early testers praise its non-intrusive help, blending seamlessly with tabs.
Market Shake-Up Ahead
Chrome dominates desktop at 69.33%, per SimilarWeb, with Edge (15.48%), Safari (7.5%), and Firefox (4.84%) trailing. But AI browsers threaten the throne. Comet rolls to mobiles, Atlas hits Macs, both Chromium-based. Firefox stands apart with Gecko, dodging the pack.
As agentic tools let AI act for you, Firefox woos the 5% loyalists craving independence. Analysts eye 2026 gains if waitlist buzz builds. Chrome leads, but Firefox AI browser’s open path might just spark a shift.
