When installing an add-on, Firefox verified the signature before prompting
the user; but while the user was confirming the prompt, the underlying
add-on file could have been modified and Firefox would not have noticed.
This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and
Thunderbird < 91.7.
