Browser Agents Gain Tab Control

ChatGPT's Chrome extension update lets the AI read your open tabs and perform actions inside them — from filling forms and sending messages to downloading files — without leaving the page. This turns the browser into an environment where third‑party agents can act on the user's behalf and access sensitive context. — This matters because consumer AI agents with tab‑level privileges shift privacy and security boundaries, concentrate new platform power, and create novel regulatory and consent questions for browsers, OSes, and web standards.
