Codex extension disappeared from UI

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I use the Codex plugin for Cursor. I have always had it pinned in my left sidebar, but after updating today to 3.10.11 it has disappeared from the list of things to show in that view.

Using Cmd+Shift+P > Codex: Open Codex Sidebar doesn’t bring it back into the view

View: Open View doesn’t list Codex in the available Sidebar options. It does appear in the Explorer section, but using that means it’s squashed under my file explorer panel rather than full height.

Steps to Reproduce

Using Cmd+Shift+P > Codex: Open Codex Sidebar doesn’t bring it back into the view

Does this stop you from using Cursor

No - Cursor works, but with this issue

I’m seeing the same issue on Cursor 3.10.11.

Codex no longer appears as its own sidebar view. Codex: Open Codex Sidebar does not restore it, and it only shows up under Explorer.

Relevant log line from Cursor:

[openai.chatgpt]: View container ‘codexSecondaryViewContainer’ does not exist and all views registered to it will be added to ‘Explorer’.

Hey everybody,

Thanks for the reports. I can reproduce this on 3.10, while it works on 3.9 (you can still download 3.9 from Cursor · Download). I’ve flagged this for the team!

Experiencing the same issue on 3.10.17. Hoping to get the update Colin speaks of soon.

22

Experiencing the same issue. Codex only appears in the Explorer section.
Last output of Codex: 2026-07-08 13:49:09.272 [error] Failed to focus Codex view error=“command ‘workbench.view.extension.codexSecondaryViewContainer’ not found”

23

3.10.20 is out but still not fixed for me :confused:

26

I am on 3.10.20 still this annoying bug is NOT fixed!

28

For me it got fixed by updating from 3.10.17 to 3.10.20 on Windows.

29

@YuriV It’s also working for me on 3.10.20!

@MisuSoft @ziv Can you share more about the actions you take that lead it not working? For example, if I run Cmd + Shift + P > Codex: New Codex Agent, I can see the Codex UI.

What do you see?

30

Nevermind, I don’t know why but it took some minutes for Codex to appear on the Explorer on the left :slight_smile:

Glad it’s fixed. Thank you and the dev team !

I found a workaround that worked for me so i am good now. Thanks so much for your fast answer @Colin , I really hope for a stable and solid integration between Cursor and Codex extension on the long run. There are MANY Cursor users that share with me this exact hope.
