Codex adds Chrome extension for browser work

This is the point where Codex stops looking like a coding-only agent and starts acting like a general browser worker. The real value is not the extension itself, but the ability to mix browser context with code execution when the task lives inside logged-in, UI-heavy systems.

• –Background tab execution is the practical win: Codex can keep moving on structured workflows without forcing a full browser takeover.
• –The feature targets tasks APIs usually miss, like dashboards, CRMs, research forms, and other account-bound web flows.
• –OpenAI’s “use the best tool for each step” framing is important: plugins handle clean integrations, Chrome handles authenticated web apps, and Codex can switch between them.
• –This pushes Codex further into web-agent territory, where reliability, credential handling, and UI robustness matter as much as model quality.
