Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. To help diagnose the issue, could you please share the following:

  1. What exactly happens when you click “Open in Cursor”?
    (Do you see an error, does nothing happen, does a different app open, etc.?)

  2. Browser console errors:

    • Open your browser dev tools (F12) and go to the Console tab
    • Then click the “Open in Cursor” button and paste any errors that appear here

  3. Protocol handler check:

    • Run this command in your terminal and share the exact output:

    xdg-mime query default x-scheme-handler/cursor

This info will help us see whether the cursor:// protocol handler was registered correctly during the .deb installation and what’s happening in the browser.

Hi, I fixed it by reinstalling: I had an old AppImage version but now the .deb install works better on Ubuntu and fixes this issue. Thanks for the help!
