Rated 5 out of 5 stars

Worked like a charm on one of my email Inboxes but not the other (I have Inboxes for 2 different email addresses). The other one is causing all kinds of problems because it is so overloaded with dupes.
UPDATE A FEW DAYS LATER ... Started working on the other folder too! Not sure why, but everything is good now so I'm changing my rating to 5 stars.

This review is for a previous version of the add-on (0.5.2b4).
