Contact synchroniser that does what its supposed to Rated 5 out of 5 stars

Of the Thunderbird addons for synching Gmail contacts, this is the best I have found so far, in terms of the amount of fields that are matched, as other programs only synch the default Thunderbird fields, without including some of the extra options that Google contact makes available.

This review is for a previous version of the add-on (0.3.4).  This user has a previous review of this add-on.
