It works! Use this one instead of the other one.

I had trouble setting up pop mail for yahoo so I ended up getting yahoo mails sent to both my primary and yahoo pop account in one email client. This gets rid of those pesky duplicates instantly. Thank you!

Works great for me in TB 3.1
Helped me recover after a crash in Windows when setting back several backups

Great work on this add-on, it worked well. The original did not respect the sent folder option, but this one does. Great options, thanks for that!

It takes some tweaking sometimes (i.e. changing up the search criteria) to get all of them, but this add-on is fantastic!! Having recently moved (or more aptly in the process of moving) to Gmail IMAP services, I do see it doesn't work very well in this context (which is really too bad, as I was counting on this extension to help me merge my online and old pop folders and weed out the duplicates)...

If you're having trouble with dupe removal on an IMAP account, file a bug using http://www.mozdev.org/bugs or at least email me. The extension does work with IMAP accounts including GMail.

Its a great tool, but it didn't work with over 50.000 messages (that could be explained by our very slow responding imapserver)
1 major drawback is that this tool needs to make a copy to the trashcan which slows it down considerably.
Please file bug reports for the first issues at www.mozdev.org/bugs .
As for the first issue, this is not true - you can choose to erase completely rather than move to trash.

Excellent Add-on!!! I had over 6 thousand emails in my inbox, lots of them dupes... I right clicked on inbox, then Remove Duplicates... a single screen wizard let me select which copy to keep for each dupe, globally, not making the selection one by one! (first copy, last copy, etc.)... And that's it! compared my cleaned up inbox with another machine running TB and both had just 3825 emails under inbox :)

Works great -- much richer than I'd have guessed! tyvm! (still on TB 2).

It appears on a first run through that this performed as advertised. If so, a lifesaver..

I am an old-time Eudora user.. So long ago that I bought it off the shelf, in a box! I later upgraded to the freeware ad-supported version. When it was time to move on to Thunderbird recently I wanted to be sure that I imported all my older messages and such. I imported the early version files into the intermediate version, then imported that into the current 3.0.4 T'bird. As you can imagine there were a LOT of duplicate messages. Trying to organize messages by folders and years made it worse. I found "Remove Duplicate Messages (Alternate) 0.3.3" and it found well over 1,600 duplicate messages. Can you imagine how long it would take to deal with that manually? "RDM alt" did the job easily in minutes helping make migration to Thunderbird a lot easier. .

Nearly really really good...
Simple to run (just select the option on right-click menu (windows)) - and very clear interface. Ran it on an IMAP inbox -it found and removed 419 dupes - great; but it missed another dozen. Why?? Still, the 419 saved a lot of mouse finger strain! - Thanks
(Using TB 3.0.3)
removedupes didn't miss anything; the other messages were simply not exact dupes, only similar. Try relaxing your comparison criteria.

In principle a good tool. I've tried it with TB 3.0.3 together with Remove Duplicate Messages (Alternate) 0.3.4.
But I've got the problem that duplicates on an IMAP Server cannot be found. I think that it is related to the new feature of TB 3.x.x where for a search on a host the Flag "Run search on server" has to be marked. This might also influence the work of Remove Duplicate Messages (Alternate) .

The add-on worked as described by cleaning up duplicate emails in all of my folders. It took a bit as I was combining many backups into one account. It was quite an undertaking, but this add-on took the duplicates from 27K+ to just above 9K in total emails. I can't express how much effort this add-on saved me. What might have taken hours, if not days to clean up, this add-on did in about 25 minutes. I'd recommend the add-on to anyone needing assistance in cleaning up their email by removing duplicates...and the $5 contribution is well worth ever dime! Great job Eyal!

well it sounds good but I wanted to check for douplicates in my local inbox and my imap inbox which did not work :-(
At least not the way I've tried it, using the inbox smartfolder

Well I installed TB 3.0.3 hoping it would fix the repeated DL problems but it didn't. downloaded and installed this program and then tried to remove duplicates and it didn't even show up. Don't guess it will work with 3.0.3 I hate to admit it but I might have to regress to Outlook. I don't think TB can fix this problem or they would have already. TB is good if you have just one computer.

I may sound crazy with so many positive reviews, but I believe this add-on does not work and never worked properly (though I used it successfully to some extent) After failure to configure it to reasonable settings that will find duplicates (stripping options to Author, # of lines and subject field), I finally left only Author and subject. Well, it returned tons of results from different authors. This app was never tested even to provide bare minimum of functionality (i.e. selecting single option should yet return correct result) I don't understand why are you guys so excited about deleting (keeping first copy) of legitimate, non-duplicate emails? Unfortunately, I cannot provide screenshots here. Otherwise, it would be total embarrassment to this add-on.
This review is for a previous version of the add-on (0.3.3).The selected options are the ones using which messages are compared. If you unchecked the 'Author' criterion, it means messages are only compared using other fields and the author may differ. Take the complement set of criteria and this will probably do what you want.

After contacting the author and getting an update for 'Deleted' (UK locale) I am now happy to use this extension.
I search on Message ID only and keep the largest at the review stage. Some size differences are trivial (eg extra header lines) but I have found that keeping anything other than the largest can result in the loss of attachments. It is not uncommon to receive two otherwise identical messages but with the attachment missing from one of them.
I use a pre-release version 0.3.4 from: www.mozdev.org/bugs/attachment.cgi?id=6300 which I have modified to remove "Set original message folder(s) for next duplicate search". Details at: www.mozdev.org/bugs/show_bug.cgi?id=22447
