CloseReview for Google Contacts by MaxR
Rated 4 out of 5 stars
Seemed to work fine, but failed to sync a small subset of most used contacts. Finally I think I figured out that it doesn't sync the contacts (from the main group) that were added to groups/lists (like mailing lists) in Thunderbird. Also it is missing the "sync now" option and is not accessible from the menu - one has to go to addons and options. It is really hard to guess if the sync is done - there is no obvious progress, only a little blinking message in status bar after re-starting of thunderbird. Finally, I switched back to Zindus, that is similar to this addon.
This review is for a previous version of the add-on (0.6.10).To create your own collections, you must have a Mozilla Add-ons account.
