Rated 1 out of 5 stars

Enigmail used to work like a charm, but broke about a year ago. Thunderbird hangs on sending emails 4 out of 5 times, and constantly requires you to kill gpg2 in order to keep working.
It's really disappointing, as it seemed to be the first extension that actually got email encryption right and used to be extremely useful.

This review is for a previous version of the add-on (1.9.8.1). 

Do you use the latest version of Enigmail? It should not make Thunderbird hang any longer. Otherwise, please report your issue at the Enigmail Mailing List and we will try to fix your problem.
