CloseReview for Zindus by RGP375
Rated 1 out of 5 stars
It worked fine for me until about 9 months ago and hasn't done anything since except screw up both address books.
I looked for another extension that works to sync gmail contacts with the thunderbird address book and finally found one that works here https://addons.mozilla.org/en-US/thunderbird/addon/8451
