Description Doran Moppert 2019-03-20 02:14:57 UTC 
Firefox will accept any registered Program ID as an external protocol handler and offer to launch this local application when given a matching URL on Windows operating systems. This should only happen if the program has specifically registered itself as a "URL Handler" in the Windows registry. 

 *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*
