Review for Zindus by StuJordan
Rated 4 out of 5 stars
Tried the google contacts addon but this seems to work better. Plus I like the fact that I can manually sync the contacts (which I can't find how to do on "google contacts")
This review is for a previous version of the add-on (0.8.24).To create your own collections, you must have a Mozilla Add-ons account.
