Codex extension not pinned on the primary side bar

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I installed the codex extension and pinned it to the primary sidebar. In the recent update, the shortcut is gone from the sidebar. But I didn’t uninstall or unpin Codex.

Now, I can only call it using the shortcut, which is inconvenient. Why is it removed? How can I move it to the sidebar again?

Steps to Reproduce

I don’t know.

Operating System

Windows 10/11
MacOS

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, this is a known issue. After updates, the sidebar extension visibility sometimes resets.

Workaround: right-click the sidebar header (or the activity bar) and enable Codex in the context menu. The icon should come back.

The same issue was discussed before: Codex IDE Extension disappears

Let me know if that doesn’t help.

I right click the sidebar and I can’t find the codex extension

Thanks for the screenshot. Yeah, Codex really isn’t in that menu, and that’s weird because everything looks fine on my side.

Try a couple options:

  1. Open the Command Palette with Cmd+Shift+P and type View: Open View, then search for Codex. After that, the panel should show up and you can pin it.

  2. Another option: Cmd+Shift+P then View: Reset View Locations to reset all panels back to the default layout.

Also I can see you’re connected over SSH because it says SSH: Dev in the status bar. Make sure the Codex extension is installed and enabled on the remote host, not just locally. With SSH connections, extensions can behave differently.

Let me know what worked, or what didn’t.

I have tried View: Open View. The codex shows up, but it doesn’t show on the menu like in my first screenshot. View: Reset View Locations doesn’t show any change.

I try to disable the extension and re-enable it. The codex does show on the menu so that I can pin it. However, when I close Cursor and open it again. The icon is gone from the sidebar. The fix looks like not persistent

I installed Cursor on my Mac OS and Windows PC. Both machines miss the codex icon on the sidebar.

Is the primary sidebar hardcoded to 4 icons only? Therefore, I can’t add Codex to be the 5th one?
