This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

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

Retrieval of the max storage amount is now done via the MozNetworkStatsManager.maxStorageAge attribute.


The maxStorageSamples property indicates the maximum number of date usage chunks stored for each type of connection.

A data usage chunk is a MozNetworkStatsData object representing the total amount of bytes received and sent during a given amount of time (this amount of time is accessible through the sampleRate property).


var max = navigator.mozNetworkStats.maxStorageSamples;


A number.


Not part of any specification.
