A truly brilliant add-on! Rated 5 out of 5 stars
I was simply looking for a plug-in to count the number of mails in IMAP accounts. Mail Summaries exceeds this simple need by providing a real upgrade to the T-bird user experience making really good use of the account splash page. Looks like this could be the beginning of a series of useful pages for each account. Installing it on all my PCs Linux/Win7/Mac-OSX right away.This review is for a previous version of the add-on (2.0).
