Stop Firefox pop-up appearing while printing badge passes

If you're using Firefox to print badge passes and you receive the message 'Confirm Dialog Preference - Prevent this page from creating additional dialogs', update the browser settings to see if you can resolve the issue.

Firefox has a default setting that can cause a pop-up to appear while you're trying to print badge passes. This is a known issue with Firefox, not WhosOnLocation. You can update your browser settings to stop this message from appearing.
