Dear John, I'm sorry that some Google users have led you to stop supporting those services.
Thank you for creating TBSync, an extension that I find very useful in my migration to TB, and thank you for allowing me to synchronize my google accounts, by to your advice I created the property "extensions.dav4tbsync.googlesupport" and everything works very well.

This review is for a previous version of the add-on (2.19).
