Sometimes it crash the Thunderbird and do full sync every time.
Full sync is significally slow, thunderbird becomes unresponsive.
calendar.threading.latency helps. But TB still CRASHES a lot.

This review is for a previous version of the add-on (2.7).

Please try changing calendar.threading.latency to 90 in the advanced config editor (Preferences > Advanced > General > Config Editor). Let me know if it works!
