When downloading files on Windows, the % character was not escaped, which 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.
