Review for Provider for Google Calendar by foss_ftw
Rated 4 out of 5 stars
This is a great addon that worked without any hassle in Thunderbird 115. That being said, I've added my GMail email account, and it looks like Thunderbird handles calendar & contact sync natively. I'm not sure this plugin may be necessary anymore.
This review is for a previous version of the add-on (115.0.2).To create your own collections, you must have a Mozilla Add-ons account.
