Review for Use Bcc Instead by Andrew P.
Rated 5 out of 5 stars
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!
