Works like a charm for me Thunderbird 60.4.0, Win7. Love the multiple options for checking duplicates.

Works great for me on Thunderbird 60.4.0 (32-bit) on Windows 10. Thanks!

I've reduced my Thunderbird hard drive footprint by about half due to an enormous number of duplicates (I'm not sure what is causing these duplicates to occur. There were a huge number in my archive from 2018, much fewer in previous years).

Sorry Mate. It's not working at all with TB 60.4.0. Which is actually NOT all your fault, since many other Addons are not usable as well after that last (unutterably) update. That's a shame.
Seems like the TB developers are incapable to include a functioning duplicate remover themself. Instaed they creating "pretty" little buttons. I am fed up with that constant updates and stopped the TB updates from now on as I think its an unreasonable demand AND a mess.

I know it may not work with TB 60.4 - I haven't attempted to get it to work with that version. As you've gathered, Thunderbird is undergoing massive changes under the hood, and currently it is a fast-moving target. Any changes I make to my extension to accommodate a certain version may (or may not) be invalidated in a couple of months. Also, the process of adaptation is not well-documented, if at all, unlike in previous versions.

If I had a lot of spare time, I'd probably do it anyway, but right now I just can't. Do check again in a few months.

For now, sadly, I can only recommend you downgrade your Thunderbird version if you want to use the extension, then upgrade back.

My apologies,
Eyal

After updating TB, I have problems to remove my douple messages. Is there a limit in mailbox size or number of messages in the mailbox? Smaller mailboxes are running, but my box with only about 7000 mails is simply stopping the TB and i have to restart. Prior to the update i had two Add-ons, which have done the job properly. Now I would be happy to learn how to fix it.

Works as advertised. Though … "Delete to Trash" means to Local Folders trash, not the account's trash. Also could do with an update to screenshots.

Totally useless to remove duplicates from sent folder "! Not searching special folders"

Enfor, to acquire the add-on, right click on the download button (not left click as you would for a normal download. This will give an option "Save link as". Then save it to a folder on your computer i.e. Download where you will remember it. Then go into the Add-on page for Thunderbird (or whatever program you are trying to add this to. There will be a gear icon near the top right of the page. Click on that and selct Install add-on from file. Then tell it the location where you saved it.

I am using this add-on on one computer, but when I try to download it now (tried on several computers) I get a message that says the file is corrupted and it will not download. ???

From the perspective of the user already.
Thank you for your answer and I am looking forward to the next version.

Unfortunately checkboxes for keeping messages still don't show up in the newest 0.61 version with my Thunderbird version of 52.8.
Otherwise it seems to work fine - finds duplicates across many folders.
A fix would be great, because now I have to delete the found copies manually in the folders.

I was saved by this plug-in saving my time.
Recently, it became TBver 60.0 b 6 and it could not be used
Because it was painful, self-responsibility, but were available to change the ".rdf".
It is use in win10 1803.
I carried out the mail about 20,000, but it ended before I finished writing this review.
Since multiple folders are also distinguished more precisely than each folder, they are always being rescued.
Thank you.

I played a lot with the settings and unfortunately I found still a lot mails as duplicate. They were the same, not attachements. Quite easy to find them even by eye. No idea why the settings don't work.

In some setting-cases the JavaScript stopped the work. Maybe it's my big postbox with ~10.000 mails (there are surely and easily much bigger possible) which is merged by some postbox versions which lead to duplicates or quadruplicates.

Then I tried the xpi-addin from Thorsten (which is warned as not compatible to current Thunderbird version). It serves more information and it's much more precise - AND it found all duplicates. Unfortunately you cannot resize the windows.

So my recommendation is - ask for the code of Thorsten and recode it for current thunderbird versions.

I don't know what I would do without this!
The only improvement that would be really good is the option to "Keep" (prioritise) messages that have been replied to. That way they could remain part of a long discussion thread & not break in the middle if I've chosen the wrong one.
How do I give you money? (No PayPal link on the Add-ons page).

I wanted to cull out some RSS element based on their website ('content-base' header), but unfortunately that extension does not offers this as a criteria for fiding dups.

Nobody's requested this before; file a feature request and we'll see.

... having said that, Thunderbird might not be exposing this to me anyway.

Handled thousands of duplicates without problems. Thanks!

Didn't know how to use it. So I tried right clicking on a folder, and well there it is! It just works, and has exactly the right options. Went through 4000 messages in <1 minute, even when set to compare the message bodies. It displays a summary of the messages it found, grouped together. It lets you compare them. It lets you delete permanently or put in the recycle bin. Just perfect, thank you!

At first this app seemed to not work. I get dupes intentionally because I have gmail also reading my main mail account, partly to have a backup on another server, partly as a defense again false positive spam blocking. By changing the default setting to be only Author, Message ID, Sent Time, and Subject, it properly removes my dupes. Unlike another app for dupe reduction, this app does not leave my keyboard delete key disabled after running it. Your mileage may vary.
