it seems to work with 3.0.1, the only problem being the install.rdf lists a maxVersion of 3.0. Change the max version and it installed fine

Remember to deactivate SIZE criteria or it won't work! It's a great extension! Thanks!

Deactivate SIZE criteria Rated 5 out of 5 stars

It's IMPORTANT TO DEACTIVATE "size" criteria. Because it's funny but it seems that duplicates are not exact copies. This means that if you choose "size" this great extension won't find duplicates. But if you deactivate that option, it seems to work great! Thanks to kevbroch, I think the author should include this in the description or add something to the extension, to explain that issue... It's a great extension! Works fine on Thunderbird 3 portable under Windows 7 64 bits...

Works well! One thing I wanted to point out is I had messages that I thought were duplicates in every sense (checked all the criteria in this plugin), but I didn't find the duplicates I wanted to detect. When I turned off "size", I did and was surprised to see that these dup's I wanted to find were the same in every way except for the size was different by 8 bytes between them. This size difference is still a mystery to me, but I feel like size might never be a good criteria to check on.

I use V0.3.3 with Thunderbird 3.0 on a German win7(x64)pro-system. I installed the addon and started using it without any issues - no complaints, just the thing I always was looking for when I used MS Outlook Express. Thank you!!

Use message ID - whenever possible Rated 4 out of 5 stars

Tried for a long time and it seemed not to work at all. Then I changed on the settings tab Message ID and sender only for identiciation of duplicates.

Now it seems to work, astonishingly quickly.

Worked well for me. I especially love the 'remove directly' option, which solved my being unable to delete duplicates because I was over quota.

If I may request anything it would be more visual feedback. When searching 30k IMAP messages I couldn't tell the difference between a hang and a running search.

Fast and Flexible - Very Useful and Fast!! Rated 5 out of 5 stars

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.

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.

Automatic for newly downloaded messages Rated 5 out of 5 stars

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.

Reduce number of "script seems to be running a long time" messages Rated 5 out of 5 stars

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.
