MDN’s new design is in Beta! A sneak peek:

This API is available on Firefox OS for internal applications only.


The sampleRate property indicates the time in seconds between when two data usage chunks are stored.

A data usage chunk is a MozNetworkStatsData object representing the total number of bytes received and sent during the amount of time defined by the sampleRate property.


var time = navigator.mozNetworkStats.sampleRate;


A number.


Not part of any specification.
