Rated 5 out of 5 stars
This is an extremely handy address book for Thunderbird. I've been using it for a year or so, and wouldn't go back to the standard address book. I particularly like the ease with which it synchronises with the Google address book.
Keep up the good work, Philippe!
(And the fault "Issue with Thunderbird 78.5.1, no longer able to access contacts from the To field" mentioned earlier has indeed been fixed. Thanks! :-) )
