CloseReview for NotTo by ViperGeek
Rated 4 out of 5 stars

When I hacked the .XPI and restarted Thunderbird 3.1, I found that the recipient list for new messages was restricted to a single To: entry. Disabling the hacked extension restored functionality.
For full support, we may have to wait/hope/pray for official support from the developer.
