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.. This vulnerability affects Thunderbird
< 60.6, Firefox ESR < 60.6, and Firefox < 66.
