Review for Remove Duplicate Messages by efrecon
Rated 4 out of 5 stars
This is a fantastic add-ons. It saved me so much time once I had had to move sent and received messages around between several (shadowed) accounts. The only problem that I had with it was to find how it installed in the user interface. You should perhaps make prominent in the description that users should right-click on a folder to access the menu entry for the extension.
This review is for a previous version of the add-on (0.1.02).To create your own collections, you must have a Mozilla Add-ons account.
