I have written a chrome extension that that uses XHR:
var request = new XMLHttpRequest;
request.open("GET", "https://www.xxxxxx.com/xxxx.php?filter=app_xxxxxx", true);
request.addEventListener('load', function (event) {
if (request.status == 200) {
console.log("len="+request.response.length);
}
});
request.send(null);
When I run this in Chrome len is 1546530
Now I installed that addon in Firefox with the very same call. When I run it in the FF developer version then len is 1546530
But when I run it in the normal FF version then len is 49403
How can this be?
