Hey, the new Marketplace is in Cursor Settings, not in the Extensions sidebar.
Open Cursor Settings (the gear icon in the top-right of the chat panel, or Ctrl + Shift + J, then scroll down the left sidebar. You’ll see “Marketplace” at the bottom.
The regular extensions panel Ctrl + Shift + X is still there and works separately.
Let me know if that’s what you were looking for, or if the issue is something else.
