Does not works with TB 45.1.1 Rated 3 out of 5 stars

Just dont do anything with TB 45.1.1

works too well Rated 2 out of 5 stars

It has various settings that work well, but it cleaned out quite a few addresses entirely. Ooops.

Well done Rated 5 out of 5 stars

Kudos to the developer. Works great, with only one suggestion; Adding a button in the review page, to merge unique info before deleting the duplicate, would make it great. Thanks for a real time saver. Five stars as is.

Simply doesn't do anything Rated 1 out of 5 stars

Installed in Thunderbird 38.7.1. Tried running it and nothing happens at all. Tried on three different installs (three separate machines) and it just doesn't do a thing.

Nice helper to organize contacts Rated 4 out of 5 stars

Thun. 38.6 on Linux. For these who wonder how to launch it it's in Contacts Manager » Tools » Find Duplicates

Finds dupes into a single list or list A and B. Let me choose which of the contacts to keep/delete, one by one or automatically.

Proposal: add some merge helpers (e.g. "Merge these fields", with a bidirectional arrow). Thank you for sharing this module!

Working for 5 hours. Not found anything Rated 1 out of 5 stars

Cant give less than one star. Starts but never completes. Win 10 Tbird 38.5.1. Tried on two different machines win 7 and win 10. Selected address book as per other reviews.
Current status removed.

I would write a review if I could find out how to engage the add on Rated 1 out of 5 stars

One would think that after installing a Thunderbird add on and restarting Thunderbird that there would be some way of finding and using the add on. That is not the case with "Duplicate Contact Manager." Nothing in any of the menus points toward it nor is there any kind of icon to click on to run it. It has no presence whatsoever on Thunderbird after it is installed. Don't waste your bandwidth on downloading this POS.

Grinds away & never does anything! Rated 1 out of 5 stars

Works ! Rated 5 out of 5 stars

Works fine on last thunderbird version !
Sorry I didn't check correctly.
MUST select the address book first
Has a progress status bar
If more then 2 duplicates (4 or five of the same) must launch again...
The only duplicate addresse plugin on thunderbird.

This user has a previous review of this add-on.

Rated 3 out of 5 stars

The interface does not provide any sort of progress indicator. This knocks off rating point for ANY software.

naw ... this provides manual removals - not what I have in mind

It just works Rated 5 out of 5 stars

Please write that it adds a menu item in the address book view. Otherwise it's hard to understand what the heck to do with the add-on. Thank you.

I am still using this plugin with TB 31.4.0. It is working perfectly. I just had to increase the maxVersion in the install.rdf file inside the xpi(zip) archive to something higher than the actual version (I chose 99.*). Why is this plugin not officially compatible with current versions? I see no compatibility issues at all.

Genial - aber Entwicklung gestoppt? Rated 4 out of 5 stars

Geniales Tool!
Warum nur hat die Entwicklung im September 2012 aufgehört???
Es gäbe wirklich noch ein paar Optimierungsmöglichkeiten...

Acceptable duplications Rated 4 out of 5 stars

I have a lot of entries where I have the same contact name but different e-mail addresses (contacts with similar names and contacts with more than one e-mail address). The add-on is flagging these as duplicates every time it is run. It would be really helpful if there was some sort of check-box to indicate to the add-on that these are acceptable duplications and not to flag them up in the future.

Apart from that it is a very helpful piece of work.

Instructions on how to run Find and Manage Duplicates (Contacts) Rated 4 out of 5 stars

Very good indeed. Thank you Marian! I agree with others users about instructions on how to use it. I found out just by applying logic. Once you install it you have to restart Thunderbird. Then go to Adress Book / Tools/ Find and manage duplicates. Hope it helps.

No instructions! How do I use it??? Rated 1 out of 5 stars

I don't see how I'm supposed to start it up.

Rated 5 out of 5 stars

Funktioniert sehr gut, im Gegensatz zur Beschreibung auf dieser Seite auch mit neuen Thunderbird-Versionen und mit zwei verschiedenen Adressbüchern.

An den Entwickler: die Anweisung in duplicateContactsManager.css "description" bitte in "#explanation description" ändern. Zur Zeit wird das untere Fenster des Adressbuchs beeinflusst, und zwar so, dass zwischen allen Zeilen ein großer Abstand erzeugt wird durch "padding: 10px".

Duplicate Contact Manager : simple mais efficace Rated 4 out of 5 stars

Rated 5 out of 5 stars

Отличное приложение, только добавьте русский.
И было бы не плохо что бы можно было бы объединять контакты, а не только выбирать один из двух.
А если еще синхронизацию сделаете по протоколу carddav, цены бы не было
