Rated 4 out of 5 stars
It currently does not work correctly with OSX mail. When you install T-Bird it recognized you have a Mac address book and creates a new book that correctly imports your contacts. Synchronizer does not see this address book. It only sees Personal and Collected. No matter what I did, I could not make this plug in work in OSX. Works fine in windows.This review is for a previous version of the add-on (0.10.2).
