I was experiencing same problem for all browsers. When user clicked "login" button, a popup opened and hanged; and unless user killed browser process, it caused a high load on CPU. If user managed to see "allow" button and click it however, then it appeared a "xd proxy" blank window and nothing happened. That was the problem.

After long investigations, I noticed my new JS code which proxies setInterval/clearInterval/setTimeout/clearTimeout methods, caused this problem. Code is as follows:

window.timeoutList = new Array();
window.intervalList = new Array();

window.oldSetTimeout = window.setTimeout;
window.oldSetInterval = window.setInterval;
window.oldClearTimeout = window.clearTimeout;
window.oldClearInterval = window.clearInterval;

window.setTimeout = function(code, delay) {
    window.timeoutList.push(window.oldSetTimeout(code, delay));
};
window.clearTimeout = function(id) {
    var ind = window.timeoutList.indexOf(id);
    if(ind >= 0) {
        window.timeoutList.splice(ind, 1);
    }
    window.oldClearTimeout(id);
};
window.setInterval = function(code, delay) {
    window.intervalList.push(window.oldSetInterval(code, delay));
};
window.clearInterval = function(id) {
    var ind = window.intervalList.indexOf(id);
    if(ind >= 0) {
        window.intervalList.splice(ind, 1);
    }
    window.oldClearInterval(id);
};
window.clearAllTimeouts = function() {
    for(var i in window.timeoutList) {
        window.oldClearTimeout(window.timeoutList[i]);
    }
    window.timeoutList = new Array();
};
window.clearAllIntervals = function() {
    for(var i in window.intervalList) {
        window.oldClearInterval(window.intervalList[i]);
    }
    window.intervalList = new Array();
};

Removing these lines solved my problem. Maybe it helps to who experiences the same.
