Hey, thanks for the report. This is a known issue. The same thing was already logged on Windows, and now it’s confirmed on macOS too.

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

Workaround:

  • Don’t move the Browser tab into a separate window. Keep it in the main Cursor window.
  • Or open localhost directly in a regular browser.

If there are any updates, we’ll post them in the main thread. Closing this one as a duplicate.
