Rated 5 out of 5 stars

Rock solid, I've been using it for years, albeit just for one feature that's probably considered minor: having a flag that turns on when a message in an IMAP folder has actually downloaded completely and can be displayed.

This add-on is the only one I could ever find that displays this information.

I can't believe I'm the only one that gets frustrated when I click on a recently-arrived message to discover that it's got a 10MB attachment and that TB won't display _anything_ until it's finished downloading the whole thing.

This review is for a previous version of the add-on (0.3.3).
