@Adrian Limmi: 1. Open the Add-ons Manager in Thunderbird, and go to the Extensions page/tab (if it isn't already open). 2. At the top of the page, click the gear button next to the search box to open a menu, then select "Install Add-on From File". 3. From here you can select the .xpi file and it should install without issue.
