What issue are you seeing?

Codex Desktop shows Chrome as connected, but @chrome automation tool is unavailable on Windows

Environment

• OS: Windows 11
• Codex Desktop: latest version
• Chrome Extension: installed and enabled
• Chrome: latest stable

---

Problem

Codex Desktop settings show Chrome as successfully connected:

已连接到浏览器扩展程序，可进行更多控制

However, when using @chrome in a task, Codex always responds with:

我这边没有可用的 @chrome 自动化工具

or cannot perform browser automation actions.

---

Reproduction

1. Install Codex Chrome Extension
2. Enable Chrome control in Codex Desktop
3. Confirm Chrome appears as “Connected”
4. Start a new task
5. Ask Codex:

@chrome open google.com

or:

使用浏览器打开 GitHub 并 fork 一个仓库

---

Actual Result

Codex says:

• no available @chrome automation tool
• browser automation unavailable
• cannot click/confirm actions

Even though the Chrome integration UI still shows “Connected”.

---

Expected Result

If Chrome shows as connected in settings, @chrome automation should be available to the agent runtime.

---

Additional Notes

This looks like:

• extension connection succeeds
• but browser automation runtime / bridge is not actually registered

UI layer appears connected, but automation backend is unavailable.

Possibly related to:

• Windows native host startup failure
• browser bridge runtime crash
• extension/Desktop version mismatch
• multi-profile Chrome attach issue
