CloseReview for Remove Duplicate Messages by wak
Rated 4 out of 5 stars
Work only one time when just installed in 45.1. Does not work when Thunderbird is shut down and reopened. To get it work I have to uninstall the module and process a fresh install on each thunderbird restart, which is a bit tedious ;)
