Review for Provider for Google Calendar by Adam Förster (SC)
Rated 2 out of 5 stars
This addon is not usable for corporate environments. If you have many calendars and something about 1000 entries in it the addon will freeze your thundebird.
This review is for a previous version of the add-on (1.0.4).To create your own collections, you must have a Mozilla Add-ons account.
