OpenAI Codex arrives in the browser with new Chrome extension

OpenAI launched a Codex Chrome extension that plugs into a user’s live Chrome session on Windows and macOS.

The extension lets Codex use existing logins, cookies, and multiple tabs to interact with websites and browser-based workflows.

This reduces the need for full desktop control and makes browser automation more practical for authenticated tasks.

It could help Codex work across real web apps and enterprise tools like Gmail, Salesforce, and LinkedIn.
