EXCELLENT PAOLO! Mozilla NEEDS to get this into Thunderbird; I popped a gut trying to import eml's with their Import option under Tools = worthless, but yours was spot on.
However, this naturally begs the question of why you can't, won't or are unable to coordinate this with them?
If we get an answer we can believe [old timer], how about a donation coming your way via 12allen and TYVM [have donated to Mozilla more than once……good people].

This review is for a previous version of the add-on (3.2.4.1).
