 'This error occurred after an enforced change in Chrome (extension) settings. However, it appears to
 'be a different error than the first one I noticed, so apparently more the change engendered multiple
 'issues. The original error is as follows:

 'Failed to load extension from:
 '\AppData\Local\Temp\Selenium\scoped_dir8860_28702\internal. Loading of unpacked extensions is
 'disabled by the administrator.
