Review for Remove Duplicate Messages by dvanee
Rated 5 out of 5 stars
I have found this add on to be very reliable. I have noticed in upgrading from 0.3 to 0.3.1 it has missed some duplicates but as I looked it has just become more precise on what is a duplicate, I played with the settings and it is working great.
This review is for a previous version of the add-on (0.3.1).To create your own collections, you must have a Mozilla Add-ons account.
