The Alternate certainly has very useful additional functionality and a much friendlier user interface. However, it does fall short on reliability and unlike the original from Thorsten Schmidt (which the author referrs to as zombie-ish) the Alternate can miss a lot (literally hundreds of duplicates) in larger accounts with thousands of messages and multiple folders.

In most cases people complain about the extension missing duplicates, closer inspection shows that the messages actually differ in some minor way which isn't checked by the other extension.

If you feel some dupes are missed, please open a bug on the mozdev bugzilla, post a folder with some missed-dupes, and we'll see...
