Review for Remove Duplicate Messages by eefalco
Rated 1 out of 5 stars
Current version is broken. It claims to find duplicates, then hangs TB. Running latest Mac Ventura, TB 102.12.0, POP from gmail.
This review is for a previous version of the add-on (0.5.3.2).To create your own collections, you must have a Mozilla Add-ons account.
