Permission prompts for opening external schemes were only shown for
<code>ContentPrincipals</code> resulting in extensions being able to open
them without user interaction via <code>ExpandedPrincipals</code>. This
could lead to further malicious actions such as downloading files or
interacting with software already installed on the system. This
vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR <
102.8.
