Rated 1 out of 5 stars

This was an awesome add-on until it upgraded. I know better than allow things to upgrade automatically (I'm a Windows user!), but I didn't think to change the default here. I had to reboot my computer today, and when I opened Thunderbird up again I got some noticed about what calendar I wanted to use. I didn't think much of it until I flipped over to the calendar tab and it was empty. Nothing I tried to get them to resync worked; I finally had to use one of the work-arounds here.

This review is for a previous version of the add-on (1.0.1).
