Rated 3 out of 5 stars

TB is now at 24.1.0, and nowhere on this site or the support site can I find whether or not gContactsync supports above v24.0.0. I hate to install this and get contacts trashed... please clarify. I will write an actual review after using (must replace Zindus).

This review is for a previous version of the add-on (0.3.6). 

The FAQ says it supports "Thunderbird 17 and later", which includes 24.1.0. Thunderbird releases new versions on a fairly regular basis so instead of updating my website for supported versions I'll announce any compatibility issues on Twitter (gcontatsync) and my blog (pirules.org/blog), and will revoke compatibility on this site.
