could have lead to a download incorrectly being saved to
attacker-influenced paths that used variables such as %HOMEPATH% or
%APPDATA%.<br>This bug only affects Firefox for Windows. Other operating
systems are unaffected.. This vulnerability affects Thunderbird < 91.10,
Firefox < 101, and Firefox ESR < 91.10.
