Great Add-on!
Just got one issue on a regular while syncing. When the date in Thunderird is invalid it considers the Thunderbird contact to be more up2date and therefore changes my google contact, but I do all my changes in Google only. hence, changes I make to some contacts will be undone/deleten/overwritten by that add-on.

* Found a match, last modified:
- Google: 1315683536515 (Sat Sep 10 2011 21:38:56 GMT+0200 (CEST))
- Thunderbird: Infinity (Invalid Date)
* The contact from Thunderbird is newer...Updating the contact from Google

Pls bugfix that!

Thanks in advance

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

Invalid (NaN) last modified dates should be treated as older than the last sync. Infinite dates would always be newer, but I don't know of a way to get an infinite last modified date on a contact without setting it manually. Could you e-mail me or make a forum post and let me know how you got this infinite date?

The next pre-release of 0.4 (0.4.0a1--see the development channel) and beyond will have a fix to treat infinite last modified dates as always being older than the last sync. I probably won't include this in 0.3 since I've never seen it anywhere else and 0.4 should be out soon.

In the future I would prefer bug reports via the forum since it's easier to discuss bugs and fixes.

Thanks,

Josh
