    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    This API is available on Firefox or Firefox OS for installed or higher privileged applications.


    The add method is used to retrieve a list of pending alarms.


    var request = navigator.mozAlarms.add(date, respectTimezone[, data]);


    A Date object representing the time the alarm must be fired.
    A string that indicates if the alarm must be fired respecting the timezone set with the date. Possible values are ignoreTimezone or honorTimezone.
    data Optional
    An arbitrary JavaScript object with data to be stored with the alarm.


    A DOMRequest object to handle the success or failure of the method call.

    If the method call is successfull, the request's result will be a number representing the id of the alarm.


    var alarm = {
      date: new Date("July 27, 2013 20:00:00"),
      respectTimezone: 'ignoreTimezone',
      data: {
        message: "Do something dude!"
    var request = navigator.mozAlarms.add(, alarm.respectTimezone,;
    request.onsuccess = function () {
      console.log('A new alarm has been set:' + this.result); = this.result; // get the id of the new alarm.
    request.onerror = function () {
      console.log('operation failed: ' + this.error);
