For those using the Thunderbird Beta and looking for a workaround for Google Calendar access, the instructions here worked for me:
https://blog.mozilla.org/calendar/2013/09/google-is-changing-the-location-url-of-their-caldav-calendars/

Short version:
- Open the calendar tab
- Add a new calendar (right-click the left panel, choose "New Calendar")
- Select "On the Network"
- Choose "CalDAV"
- Set location to: "https://apidata.googleusercontent.com/caldav/v2/[your-gmail-address]/events"
(Replace [your-gmail-address] with your gmail. Don't include quotes or square brackets.)
- Enter a display name for your calendar and set the email account.
- When completed the Google account login window will appear. Enter gmail account and password.
