I tried moving a lot of messages from one folder to another, and Thunderbird crashed. I started it up again and finished the move, but once that finished, many of the messages were duplicated several times in the destination folder. I looked up "Remove Duplicates" add-ons, but none of them appear to be compatible with the latest version of ThunderBird. What is the best way to eliminate duplicate messages from TB version 78.1.1?
