CloseReview for Provider for Google Calendar by yadfa
Rated 5 out of 5 stars
I love it.
Here is a bug.
Preferences->Security->Passwords->User master password
This conflicts with the addon and makes thunderbird almost unusable. I had to remove the add-on, remove the master password and reinstall the add-on.
