I've got Thunderbird 3.1.11 (on Ubuntu 10.4) and I downloaded Enigmail 1.1.2. Then clicked on Tools>Addons and then clicked on the button [Install...] to find the extension I just downloaded. However when I clicked on the downloaded extension and then clicked Open nothing happened. Ie the extension didn't appear in the Addons window. Is there another way to install this extension or have I got the wrong version perhaps? I've used Enigmail before and found it very easy to use so I'd like to stick to it. cheers

Questa recensione riguarda una versione precedente (1.3.2) del componente aggiuntivo.
