CloseReview for Duplicate Contact Manager by doc.martin
Rated 4 out of 5 stars
Generally did a good job but it did miss a few duplicates that I had to delete manually. None-the-less it saved a lot of time - worth trying.
This review is for a previous version of the add-on (0.6).To create your own collections, you must have a Mozilla Add-ons account.
