Advanced Remove Duplicates is an extension which extends folder-context-menu with a button to delete duplicate messages.
Please note that the development of this extension is discontinued.
If you need more features please have a look at "Remove Duplicate Messages" by Thorsten W. Schmidt.
I dont think that there is need for two extensions doing the same thing. Kind regards M. Abraham.
