Review for Provider for Google Calendar by Damiaan van Vliet
Rated 5 out of 5 stars
For those who had also problems since yesterday with this plug-in I may have a solution. For me it was simple, just update Thunderbird and reinstall this add-on with version 0.32
This review is for a previous version of the add-on (0.32).To create your own collections, you must have a Mozilla Add-ons account.
