Well, unsubscribing, deleting the add-on, re-installing the add-on, and re-subscribing to the calendar did NOT fix the issue. It gets stuck with a blank dialog where the authentication should be taking place.

I even un-installed/re-installed Thunderbird and repeated the steps above. Same result. Seems to be something about the existing profile I think. I did a completely fresh install on a Debian system with no prior profile and was able to add my calendar successfully. However, when I stopped/started TB, my calendars were blank and had to be re-added to get them back :-(
