It does what it claims. I've installed "Use Bcc Instead" successfully for Thunderbird running on Windows 7 and Linux, but since I usually use SeaMonkey for my email needs, I'd love to see this extension adapted to work with SeaMonkey, too!

This review is for a previous version of the add-on (3.2.1).
