Rated 5 out of 5 stars

This is a great plugin. I have been using it for over 5 years. As of last week unable to authenticate to new calendars. I tried the cookie setting but not working. Something change with either Thunderbird or Goggle. Please advise on possible fix. Let me know if you need any additional info to help.

This review is for a previous version of the add-on (3.1). 

Please get back to me via the support email and I am sure we can sort things out!
