CloseReview for Provider for Google Calendar by Joe Emenaker
Rated 4 out of 5 stars
I have been using this add-on for a couple of years now. It is the only thing which I have found which gives me read *and* write access to my Google calendars.
*However*, the 1.0.2 update seemed to break something. Whenever I tried to dismiss or snooze a reminder, I got "This item has recently been changed on the server..." and I am given a choice between "Discard my changes and reload" or "Submit my changes anyway". Whichever one I chose, I got the same reminders, and trying to snooze/dismiss them popped up the "Item has changed..." dialog again. Fortunately, I tried deleting the calendar and re-adding it and the problem went away.
