Answer
There are two issues with Mozilla Calendar that we are aware of. The Mozilla development team is aware of both and will be working to correct them.
- It gives an error if you try and access an empty calendar.
- It does not like tasks that do not have either a start date or a due date. They are not editable and information may be lost in some parts of the Mozzila GUI. Mozilla itself is not able to create such entries but other calendaring clients may do so.
