CloseReview for Thunderbird Biff by ffKool
Rated 1 out of 5 stars
Developer's site states that to install this into TB, you must save it to disk. However, the link just leads back here, and there is no option to download the file directly -- only "Add to Firefox".
Can you give us an updated/correct link please?
