Rated 4 out of 5 stars

Hi, tested, this module is full of many good functions to discover such as: at startup it imports the native Thunderbird address book, nothing lost, easy export and import, color for each book, choice of fields to display in the list for each book, etc. I did not find the function to synchronize the changes to the native notebook. Thanks.

This review is for a previous version of the add-on (44.1). 

synchronization with native notebook (or with any local PC) not yet possible ;O)
