How Codex app with Chrome skill choose Chrome profie?

[doggy8088]

I have multiple Chrome profiles. The Codex app with the Chrome skill seems to choose a different profile at random. Is it possible to configure which profile the Codex app uses?

I do not see a documented Codex setting for “use Chrome profile X” yet.

The current behavior seems to be based on the Chrome profile where the Codex Chrome extension is installed, enabled, and connected. The docs specifically say that if you use multiple Chrome profiles, you should make sure you are using the same Chrome profile where the Codex extension is installed, and install/enable the extension in the active profile.

So the most reliable workaround is to make one dedicated Chrome profile for Codex:

1. Create or choose one Chrome profile, for example: "Codex".

2. Install/enable the Codex Chrome extension only in that profile.

3. Disable or remove the Codex Chrome extension from your other Chrome profiles.

4. Open Chrome using the "Codex" profile.

5. Confirm the Codex extension in that profile shows "Connected".

6. In Codex, make sure the Chrome plugin is enabled.

7. Start a new Codex thread before trying @Chrome again.

If Codex still opens or attaches to the wrong profile, try this reset sequence:

1. Close Codex.
2. Close all Chrome windows.
3. Reopen Chrome directly into the desired profile.
4. Confirm the Codex extension says "Connected".
5. Reopen Codex.
6. Remove and re-add the Chrome plugin if needed.
7. Start a new thread.

For now, I would avoid installing the Codex extension in multiple Chrome profiles at the same time, because that makes the active/connected profile ambiguous.

This would be a useful feature request: Codex should expose a Chrome profile selector, or at least document exactly how it chooses between multiple connected Chrome profiles.
