Review for Provider for Google Calendar by BayGCP
Rated 4 out of 5 stars
Working well on 68.2.2. My Linux distro had v60 and baked in lightning. I had to uninstall all mozilla, reinstall FF and TB from the web, delete .local TB folder, and then install cal provider from add-ons, bypassing my distros repo. No issues now.
This review is for a previous version of the add-on (68.2.1).To create your own collections, you must have a Mozilla Add-ons account.
