Review for Remove Duplicate Messages by Bill
Rated 1 out of 5 stars
This will not install on my TB 78.7.1 (32-bit). It complains that the file is corrupt. I've tried this a few times over a couple of weeks. Always says the download is corrupt.
This review is for a previous version of the add-on (0.5.1b2).To create your own collections, you must have a Mozilla Add-ons account.
