Review for Provider for Google Calendar by Todd Knarr
Rated 5 out of 5 stars
The rating's for the smooth performance of this add-in over the years. The latest versions (1.0 and 1.0.1) are having problems related to the add-in's request quota and OAuth. I expect those'll be resolved soon. This is the first glitch I've seen in several years, which is a welcome change from a lot of software out there.
This review is for a previous version of the add-on (1.0.1).To create your own collections, you must have a Mozilla Add-ons account.
