The document discusses Firefox OS, an open source mobile operating system developed by Mozilla. It provides an overview of key aspects of Firefox OS including its use of open web technologies like HTML5, its architecture consisting of layers like Gonk and Gecko, and the various web APIs available to developers to access device capabilities. It also covers topics like app security, packaging vs hosting apps, and tools for developing and testing Firefox OS apps.

cursor.onerror = function() {
console.error("Error in DeviceStorage.enumerate()", cursor.error.name);
};
cursor.onsuccess = function() {
if (!cursor.result)
return;
var file = cursor.result;
// If this isn't a video, skip it
if (file.type.substring(0, 6) !== "video/") {
