Review for Remove Duplicate Messages by Firefox user ea39c5
Rated 5 out of 5 stars
Didn't know how to use it. So I tried right clicking on a folder, and well there it is! It just works, and has exactly the right options. Went through 4000 messages in <1 minute, even when set to compare the message bodies. It displays a summary of the messages it found, grouped together. It lets you compare them. It lets you delete permanently or put in the recycle bin. Just perfect, thank you!
