    I am trying to clean up my addresses and found numerous duplicate addresses in the Mac OS X Address Book in Thunderbird. Looks like this address book is a "read only" in Thunderbird. Is there someway to clean up the duplicate addresses? Sometimes there are 4 separate entries for one individual address - tried to use the add-on for duplicate entries but that does not work in the Mac OS X Address Book. Any thoughts or suggestions would be much appreciated.

    I don't use Thunderbird, so I cannot offer specific help with your issue. A new version of Thunderbird, V45.6, came out the other day, and apparently it contains a number of crucial security fixes:


    You can get the new version from here:


    When I did a google search of "How to clean up duplicate addresses in the Mac OS X Address Book in Thunderbird", here are the results (ie, all the "hits"):


    A couple of those mention add ons for Thunderbird, including one entitled "Duplicate Contact Manager", but you already mentioned trying one without success.
