CardBook

Rated 5 out of 5 stars

Address autocompletion works much better now, at least in Mac OSX, as it puts the most used contacts first when you compose a new mail and start filling out the recipients names.

This alone is worth 5 stars in my humble opinion.
The other features (I need to use) also seem to work as expected.
Works like a charm when connected to Mac OSX Server address book service, which is a VCard service.

If you are on a mac, I'm sure you'll find this add-on to be "the missing Thunderbird address book" that will fill an important gap compared to other clients.

Please note that all of the above is my humble opinion.
