Wonderful! This works beautifully with large IMAP folders (>1k messages).

I have just two complaints:

1. Needs an override option to search special folders like Sent.

2. It would be nice if it automatically preferred duplicates that have been replied or forwarded (the green and purple arrows).

Already possible...

1. In the extension's options window, uncheck 'Skip Special Folders'.

2. Make the message flags field visible, sort by it (click the appropriate column once or twice for the reverse order), then select 'Keep First'. This does the job in most cases, as the HAS_RE(ply) is copy is kept, or removed, depending on the sort order.

Very powerful add on Rated 5 out of 5 stars

Very powerful add-on when you need to clean up a mail box.
All is configurable, the using is very easy.

Fantastic add-on!! Rated 5 out of 5 stars

Having several mailboxes in Thunderbird that have persistently downloaded duplicate messages leaving me with thousands of emails to sort through, I was ready to ditch the lot and start again with a different email client but this add-on has done an amazing job of clearing the mess up. It installs easily, then a simple right-click on the folder that you are interested in gives an option to 'remove duplicates'. The user-interface is very clear and simple - you have the opportunity to check before deleting the duplicates and you can delete them all immediately or move them to your deleted files if you are not sure about getting rid of them immediately.

Initially I found that not all my duplicates were discovered - I contacted the writer, Eyal for help (thanks for the very quick & helpful response Eyal). The issue was easily solved by changing the Message Comparison options (Tools menu -> Add-ons -> Remove Duplicates -> Options button) - removing size from the list.

A fast & effective tool - highly recommended.

Better than the other - this one can delete permanently! Rated 5 out of 5 stars

I have used this as well as the other "Remove Duplicates" and like this much better.

The other one does not have the option to permanently delete the dupes. When I would find messages in the Trash, I was often not sure whether they had been deleted intentionally. To be sure, I had to waste time moving them back to the original folder and de-duping again, then deleting them from the Trash.

With this extension, I simply choose to delete them permanently the first time and I need never wonder about that.

Good tools, very useful.
It may be very interesting to be able to check duplicate from different accounts.

Considering Tags Rated 5 out of 5 stars

Just a tip. If a message is tagged, it means that some action was taken, so the tagged message should have some priority over the one without tags regardless of being unread or not. This could be an option.

Great Job the old addon definitely needed a rewrite!

Fantastic Product Rated 5 out of 5 stars

Fantastic product. For those who don't have web IMAP, and/or remote access to email servers, but have an alias where all email is copied to just in case you are away from the office, then this is the answer for you.

I can now download from any server, and this clears out the emails I have already downloaded from the alternative server.

Fantastic. Before now, it was just a pain in the *** to have a duplicate of every message.

Many and all Thanks to Eyalroz!!!!!!

p/s I had the same suspicions as NM below, but discovered that the headers in messages from one server was different to the message from the other server. (Obviously I know). This meant the message size was different. So I deselcted the message size criteria, and selected all other criteria and bingo. Every single duplicate was detected. I have a backlog of 10 years worth of messages it did the lot.

Thanks again!!!!!!!!!!!!!!

A nice window and it works fine. There is no risk because it searches firs and asks to confirm later.

I have found this add on to be very reliable. I have noticed in upgrading from 0.3 to 0.3.1 it has missed some duplicates but as I looked it has just become more precise on what is a duplicate, I played with the settings and it is working great.

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.

Better double-check that...

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...

I'm having the same problem as trishf42; after upgrading from 0.3 to 0.3.1 it's not detecting any of my messages as dupes. If I play around with the settings I can get it to detect some dupes, but not all; downgrading to 0.3
