 > Looking at https://bugzilla.mozilla.org/show_bug.cgi?id=1245842 it seems
 Mozilla is not dual-signing things either. Instead, if I understand it
 correctly (https://bugzilla.mozilla.org/show_bug.cgi?id=1245895), they are
 redirecting users with older systems to binaries signed with SHA1 while
 properly supported ones get SHA2 signed installers.
 This is for outdated pre-SP3 XP and pre-SP2 Vista. You shouldn't support
 Windows installations without the latest security updates.
