The main differences are: 1. with mozAlarms you have to specify a date, here we have an interval. 2. with this API we are free to postpone some task in order to avoid overload of the phone: no more than 1 task running at the same time (if it takes less than 10 secs~). 3. wifiOnly tasks 4. the tasks can be configured by the settings app (using navigator.syncManager). This means, for instance, that the use can decide how often sync the mailbox.
