By exploiting an Open Redirect vulnerability on a website, an attacker
could have spoofed the site displayed in the download file dialog to show
the original site (the one suffering from the open redirect) rather than
the site the file was actually downloaded from. This vulnerability affects
Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
