Very useful, however its accuracy in detect dupes is not perfect (it miss just a few ones) and seems not possible to delete dupes in personal IMAP folders (you've to move them in a local folder > search for dupes > put back in imap folder).

This review is for a previous version of the add-on (0.3.12).
