Codex Chrome Extension
OpenAI's coding agent now works inside Chrome on macOS and Windows, running tasks across tabs in the background using the user's signed-in browser state.
Details
- Available on macOS and Windows; install from inside the Codex app
- Works in parallel across tabs in the background without taking over the browser
- Codex picks the right tool per step: plugins when they fit, Chrome when it needs a logged-in website
- User controls which sites Codex is allowed to use
Best for
agent tasks that need a logged-in website (LinkedIn, Salesforce, Gmail, internal tools)
When to use it
a job needs a signed-in app the agent cannot reach via plugins or API
Who benefits
developers and power users already running Codex who want it to drive their browser
