Review for Provider for Google Calendar by Tinet Erahe
Rated 5 out of 5 stars
Well done. I love this. An useful extension. There's a same one in Thunderbird add-ons, and it doesn't work at all. (s.t wrong?)
This review is for a previous version of the add-on (0.4).To create your own collections, you must have a Mozilla Add-ons account.
