I think that this would be a good program but, there is one slight problem. I can't install it on the 3.1.15 version of thunderbird.

This review is for a previous version of the add-on (1.3.2). 

Old version

Please download the appropriate version of Enigmail for Thunderbird 1.3.x from http://enigmail.mozdev.org/download/
