There is no very quick decoding method in Thunderbird. For decoding uue 
sections I open standard editor Notepad; then I select and copypast all 
the sections into the open text file and save it as a *.uue file. Then I 
use Total Commander to decode a uue file.

But Fidolook (a fidonet extension for Microsoft Outlook mailing program) 
can combine many messages with uue sections and show the final picture.

Bye, Paul!
