Rated 4 out of 5 stars

The latest release seems to work fine on both Thunderbird 5 and 6. The only glitch that I'm seeing is that you have to double click the send icon when sending messages instead of single clicking. The same applies to the keyboard shortcut - Ctrl -Enter needs to be pressed twice to send.
