Love this add-on - it has done everything we have needed it to do. It has some great features and syncs very well with Gmail. My wife and I can now back-up contacts and share them between us too.

One caveat - make sure you back-up your contact lists before using it, and preferably periodically while using it, to make sure you can restore any hasty changes.
