Extremely useful to synchronize appointments on my various devices (Android, Windows, Linux).
Buggy in Version 78.3.2: Removed the end date from all my weekly appointments. Had do use a work-around (set the end date over the Calender displayed in Firefox.

This review is for a previous version of the add-on (78.0.1).
