But, please, how can I change language?
Thank you.

Questa recensione riguarda una versione precedente (5.9.1) del componente aggiuntivo. 

the language of your Thunderbird version is used. So if you have installed Italian Tb, then you will see the Italian translation of QF. You can also change the language from Thunderbird using General / Language & appearance / Language. Use the "Set Alternative" button to download and activate other languages. I do most of my translations with google translate, and some of them may be incomplete, for a full list of what;s there check my github page: https://github.com/RealRaven2000/QuickFolders/tree/ESR91/_locales
