CloseReview for Provider for Google Calendar by ZehHa
Rated 5 out of 5 stars
You should make sure to use the corresponding and compatible versions of Lightning and Gdata Provider. As I'm working with SeaMonkey (latest version 2.26 works fine with Lightning 3.1b1, Gdata Provider 0.30pre, and German language pack) I cannot tell you with versions you need. Could be helpful to look into the support forum:

And to look here:
