Review for Provider for Google Calendar by jplevene
Rated 1 out of 5 stars
Since version 68 of Thunderbird, this plugin really doesn't work well, then again, neither does Thuderbird using CALDAV to a google account. Enter a Google account, do the login and then nothing appears in the list to setup the calendar
V68 of Thunderbird has been a disaster
