Does HTML 5's BlobBuilder() still work in Google Chrome?
It's gone or deprecated. Use the new Blob constructor.

In your tutorial instead of:
var bb = new (window.MozBlobBuilder || window.WebKitBlobBuilder || window.BlobBuilder)();bb.append(data);var blob = bb.getBlob();Do:
var blob = new Blob([data]);
