TB52.4, the box appears, but without any addres book selection device, and 'start' does nothing.

If two contacts are exactly the same, no automatic merging is possible.

Tried installing, removing and reinstalling. It does not seem to do anything at all. The window comes up. I make my selection to collect all duplicates and click START but nothing ever happens. TBird ver. 52.2.1

Does what it is supposed to do, the side-by-side view of (near) duplicates allows efficient screening and merging of entries

The window « search » appears well (and in french automatically, nice), but when click on START, nothing seems to happen.

EDIT : at the end, that works but not on ALL addresse books together… So not very usefull tool because i need to find doubles between all differents address books.

RE_EDIT : well, i tried one more and i can compare two address books together, but not all adresses books in one action.

Last update is from 2012 but still works on Thunderbird 45.4.0 (though only by selecting one address book at the time). I would like to translate this add-on to Portuguese European pt-PT, developers please submit your add-on on babelzilla.org for free localization

This extension works well and works with TB 45.

However, it has a bug: if "All Address Books" is selected, if does not work as expected (dialog show up but does not let you select which addess books you want to compare.

You have to click on an address book first, then it will display its main extension dialog properly.

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

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.

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.

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!

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.

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.

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.

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