Thunderbird DropMyRights

THUNDERBIRD DROPMYRIGHTS SETUP - IAN MUTCH

When using the shortcut to THUNDERBIRD DROPMYRIGHTS, which is created by the installer, you will be using Thunderbird with reduced rights. This makes it more difficult for malware to be installed on your computer, though not impossible. Thunderbird is not altered in any way, you are simply using it with reduced rights when you use the THUNDERBIRD DROPMYRIGHTS shortcut.

to confirm that you are running Thunderbird with reduced rights. (Right click thunderbird.exe>Properties>Security. It will show BUILTIN\Administrators Deny,Owner.)
