Review for Provider for Google Calendar by David
Rated 5 out of 5 stars
This add-on is a Godsend. Integrates with the Lightning add-on for Thunderbird and provides Google calendar access.
There were initial problems with freezing but it was the Birthdays Calendar add-on that was found to be the culprit. I have since unsubscribed from this Birthdays calendar and everything is working great. Thank you...
Can you try unsubscribing for the Birthdays Calendar? This calendar is known to cause trouble for some reason.
