Steps to Reproduce

Open a browser tab
Move it in an external window
Go the page you want ton inspect

Hey, thanks for the report. This is a known issue. The Browser tab crashes or becomes unresponsive after you move it into a separate window.

Main tracking thread: Bug: Browser tab unresponsive after moving to new window (v2.4.22)

Workaround:

  • Keep the Browser tab in the main Cursor window
  • Or open your page directly in a regular browser

The team is aware. We’ll post updates in the main thread. Closing this thread as a duplicate.
