sweet Rated 4 out of 5 stars

if they had an option of 9.5 I would give that. it would be great if existing google calendars where able to be converted either automatically or manually to full read/write with this extension.

This review is for a previous version of the add-on (0.3). 

Fixed in the latest nightlies
