Very nice addon--thank you, Amulya. For asbin, by going into Thunderbird's about:config ("Tools -> Options -> Advanced -> General -> Config Editor (button)" I was able to modify extensions.follow_up_ext.calname from "Follow-Up" to the name of my Google Calendar in Thunderbird's calendar list. The follow-up event now syncs to my Google Calendar. That seems to work fine as far as I can tell so far. Maybe that helps.
