→Silent installation of Thunderbird extensions
</package>
</source>
* Basically, it means you have to copy the folder named similar to {8845E3B3-E8FB-40E2-95E9-EC40294818C4} to your "%PROGRAMFILES%\Mozilla Thunderbird\extensions" folder
* when Mozilla Thunderbird is next started, a new extension is detected automatically - you can verify this in Thunderbird using Tools -> Extensions
or you can use this script
<source lang="xml">
