I open firefox and a dropdown window appears with this message. DragDropUpload exception in track ReferenceError: nsDragAndDrop is not defined. I ca click on canceler OK. Clicking OK causes the window to close and immediately repeat. I can quit firefox.

Is this a problem with an extension (FireFTP)?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • Do NOT click the "Refresh Firefox" button on the Safe Mode start window
