How do I restore my calendar after a Thunderbird crash?
While attempting to print out an email (no attachments) Thunderbird crashed. After restoring Thunderbird (and able to view all my email accounts) I opened my calendar via the "Events and Tasks" tab. The calendar opens up but no content that I had created in the calendar or that came in from outside meeting invitations. If I go directly to Google calendar via Firefox, the contents are there. However I cannot access my google calendar from the Thunderbird calendar. Google Calendar shows as an option under "calendar" to left of the actual calendar.

I remember having had a similar situation.
Perhaps in the add-on menu the Lightning extension is disabled or no longer visible? If so, re-enable it.
Alternatively, you may disable (or even uninstall), quit Thunderbird, then enable (re-install); I think this is what I did. Data should not get lost, but of course you'd always rather backup before doing any critical procedure.
