Rated 5 out of 5 stars

It's a wonderful tool and essential for secure mail sending. It is easy to use under Linux and Windows upto Win7.It doesn't work with Thunderbird 24.1.1 and Windows 8.But at least it is better to do without Win 8 than Enigmail!
Hello Patrick, unfortunately I don't see a possibility to answer to your statement directly, so I would like to tell you in this way, that I made the experiences with Enigmail and Thunderbird in Win8 by my self. I have screenshots, which show, that Enigmail 1.9 is not compatible to Thunderbird 24.1.1
I run several Linux systems as well as Win 7/8/8.1, but it is only in Win 8 and 8.1. not compatible.
I don't know why.

This review is for a previous version of the add-on (1.6). 

Why would Enigmail not work on Windows 8? I cannot see any reason for this, and I know of many users who use this combination successfully.
