How to reproduce

  1. Browse to
  2. Click the ABP icon
  3. Select "Block element"
  4. Click on the Google logo image
  5. Click on the the "Add" or "Cancel" buttons

Observed behaviour

Nothing appears to happen when either button is clicked, but the following exception appears in the console:

Scripts may not close windows that were not opened by script.

Note: When the "Add" button is clicked the filter actually _is_ added, but since the window doesn't close that is not obvious to the user!

Expected behaviour

Both buttons should close the window when clicked.
