Review for Remove Duplicate Messages by Martin Farrimond
Rated 2 out of 5 stars
Potentially great when re-creating/re-importing emails, but not working reliably on Thunderbird 115.4.3 on Windows 10. Intermittently crashes Thunderbird resulting in lost emails and corrupted mbox files. Would otherwise give 5 stars.
This review is for a previous version of the add-on (0.5.4b5).To create your own collections, you must have a Mozilla Add-ons account.
