Rated 4 out of 5 stars

Quite a good add-on, but it doesn't work right when you also use Thunderbrowse. The addressbook buttons "New Contact, New List ..." then have no function. But because I like to work with AddressBookTab I have disabled Thunderbrowse. Would be great I could use both.

This review is for a previous version of the add-on (1.3.2). 

I'm currently rewriting the addon in order to introduce a new tab type specifically for addressbook. This improvement will probably solve a lot of interaction with other addons. I will test all reported trouble and try to solve them.
