I got this add-on to clean up duplicate messages coming in from Webmail, and the default settings work great to clean up these dupes.
Other times, I'll put the original emails and their forwarded/sent copies in the same folder, then change the criteria so I can find the dupes and select the copies I want to keep.
The ability to select so many different combinations of search criteria is very useful. Add to that, the fact that you can see the list of messages found and easily select which ones to keep, is a safeguard I appreciate.
The fact you have the option to move the dupes rather than delete them is another one of this add-ons built-in safeguards. Automation is great--but it can be a curse when it comes to deleting information. This add-on is well designed, and well thought out.
Great job by the developer!!

This worked nicely for me. At first, I had it checking too many criteria (body). It was taking a long time. I changed the search to "from", "to", "sent time", "size", "subject" and "folder". It is now fast and effective.
Nice job.

I use this addon sometimes. For backup, I always BCC messages to myself, so many duplicated messages are in my mailbox. This completely clears those duplicated messages with easy operation.

Flawless execution and amazingly fast! Couldn't ask for anything more.
(Running it on TB 3b2 / TB 3b3, with Penelope.)

Works perfectly for me on 2.0.0.23 (20090817), and is surprisingly fast.
Thank you, I used to have lots of duplicated RSS feeds, now to delete them I need only a second.

Is a decent extension, but doesn't work anymore. It says "Searching for duplicate messages... (2543 messages hashed)
Duplicate message search complete." but then it never shows a dialog.

This is very good extension. Has many options for good matching. I used it very long time. My only problem is that our mail server often sends one email several times when the recipient is included in more then one alias. Unfortunately it is not possible the extension to be created in a way do this automatically on new email receiving.
But I found there is a config property mail.server.default.dup_action that can do this.

Thanks for the extension I still use it when I need to compare many emails.

Works great. Used on merging of 80K message files. To avoid the script timeout problem:
Tools -> Options -> Advanced -> General -> Config Editor... -> {Right click on} dom.max_script_run_time -> Modify -> {a longer time in seconds}
I used 500, and only had to click on the script timeout message once. I checked the Windows Task Manager, and when Thunderbird is waiting for the pause window, it stops working. Bumping up this number just prevents it from prompting for so many error messages.

Did what my IT department didn't manage after messing up :)
Nice graphical interface where easy to understand options were given. Also gave me full control of what do delete and not in a very user friendly way. Nothing was permanently removed.
I did miss an icon somwhere to know how to access the software.
A button with a nice Icon is available for addition to the main toolbar - do 'Customize Toolbar' and you'll find it.

it is disabled when be used on in-box,why?And does it support Simple Chinese?
This review is for a previous version of the add-on (0.3.2).removedupes skips by default all special folders except for the Inbox. However, for it to go through the Inbox, the Inbox' name and the name removedupes _thinks_ the Inbox has have to match. So if the localization is wrong or missing, removedupes will skip the Inbox. You can fix this by unchecking 'skip special folders', or setting the removedupes.allowed_special_folders pref to the appropriate regexp (e.g. ^blah$ if your Inbox' name is blah).
As for Chinese support - it works for Hebrew, so it should work for Chinese too.

Successfully removed >11000 duplicates - took about 30 minutes on my slow computer - I had to respond to the "script may have stopped" message several times.
It did not remove any messages the first time - may have crashed? - but I tried it again. The second time it ran (with the same "script may have stopped" message) and it successfully removed all the duplicates - I just had to be patient.
By the way the 30 minutes includes both the first time and the 2nd time I ran it. and also includes the time it took thunderbird to compact the folder after removing the duplicates.
Great - now I have regained at least 900mb disk space back!

This is absoultely fantastic and saved me hours and hours of searching after migration.
But one feature should be added: The Search should also be possible over multiple accounts, because I use to file messages in folders and receive sometimes identical messages to two email-accounts.
I tried to select my accounts in the left panel and tried a search, got results, but the plugin does not show in the "Folder" column, which account the message belongs to.
But still this is a great help!
You can search over multiple accounts - just not in Thunderbird. In Seamonkey you can use ctrl+click to select multiple folders and accounts. It\'s not my fault that TB is a bit bastardized...\r\n\r\nAs for the folder column - click the column selector button and add it; it\'s not missing, it\'s just hidden.

When you re-creating your email account and have old emails, then you receive another 70% of the same emails this addon is the best so far i've seen. It lets you to delete older copies so next time you do not receive the copies of the same emails again.

Wonderfule add-on: quick and efficient.
The most part of times it isn't useful, but when you have some import going wrong (from outlook...) or if you lave ckean file...

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).
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 when you need to clean up a mail box.
All is configurable, the using is very easy.

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.

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.
To create your own collections, you must have a Mozilla Add-ons account.
