I have to post here because at:
http://fux.zuhage.de/attachment_sizes/
there is no way to contact Alexander Ihrig who seems (I don't understand German well) to have made this extension compatible with TB 3.x.
Tis is to say that I found a bug in the 0.0.9 version. That is: if you drag and drop an attachment from desktop or from any folder inside Thunderbird message to be sent everything is ok, BUT if you try to drag and drop an attachment from an already sent mail or from a rceeived mail to a new message, then you will succeed but NO SIZE size appears near to the attachment file name.
