Rated 1 out of 5 stars

I've installed 2.0.1 on Windows 7 and Thunderbird 3.0.4. When sending mail, an error like "Temporary file cannot be opened, check Temporary directory preference". The second time Send button is pressed, there's no error.

Đánh giá này là cho một phiên bản trước của tiện ích (2.0.1). 

I'm not sure what's causing that, or how to fix it, but I do know about it. Try the beta channel version and let me know if there's any improvement.
