This extension works exactly as needed, even works without problems in seamonkey (after converting it in the http://addonconverter.fotokraina.com/ converter).

It would be possible to add an item to the context menu of the mail folder (as it does, for example, addon "Remove Duplicate Messages (Alternate)")?
