Rated 5 out of 5 stars

This is the perfect add-on for those wanting to maintain address books between different PCs, and it is manna for those who want to avoid giving contact information to Google et. al. despite privacy promises.

I've been looking at automated export options to different address book formats to accomplish the same thing. Mr. Gersdorf created exactly what I needed without having to mess with all that. Well done!

This review is for a previous version of the add-on (0.10.2).
