Firefox is testing a new feature called "AI Window," giving users a dedicated space in the browser to interact with an AI assistant when they want it. Mozilla frames the tool as a controlled chat panel that can support browsing tasks without reshaping how people use the browser. The company says users decide if, when, and how the feature appears, and they can disable it at any time.
Mozilla positions this approach as a contrast to browsers like OpenAI's Atlas, where AI is either always present or completely absent, or, in Mozilla's view, nudges users into open-ended chat sessions. With AI Window, Firefox aims to maintain its identity as a fast, private, and independent browser, treating AI as an optional layer built around transparency and user control. Those interested can join Mozilla's waiting list. All AI browsers released so far have already faced significant security issues.
OpenAI is testing a group chat feature for ChatGPT in Japan, South Korea, Taiwan, and New Zealand. Users on Free, Go, Plus, and Pro plans can chat together with other people and ChatGPT in the same conversation. The system won't pull in personal memories from private chats. ChatGPT jumps in based on context or when someone addresses it directly.
The responses run on the GPT-5.1-Auto model. Participants can join through invitation links, manage groups, and customize ChatGPT's settings individually. Users under 18 get automatic content restrictions, and parents can disable the feature entirely.
