Sync Google Contacts with Thunderbird

I use Thunderbird as my email client of choice, and I use it to access my Googlemail account via imap. Everything works just splendidly, except for sharing contacts.

Fortunately I've found Zindus, a rather splendid add-on for Thunderbird that keeps your Thunderbird and Google contacts in sync. Everything you need is to be found on the Zindus website, but it seems pretty idiot-proof, and so far seems to work just like it ought to. Well done Zindus.
