Review for Provider for Google Calendar by Karthik
Rated 3 out of 5 stars
This is so far the most reliable add-on for google calendar. But it comes with a bunch of bugs related to calendar event reminders. I'm waiting for the bugs to be resolved.
This review is for a previous version of the add-on (102.0.3).To create your own collections, you must have a Mozilla Add-ons account.
