In this particular case, you aren't making an ajax call at all, instead you're making a JSONP request. Luckily, these are incredibly easy to replicate and work in all browsers.

var s = document.createElement(script),

    callback = jsonpCallback_ + new Date().getTime(),

    url = http://forexplay.net/ajax/quotes.php?callback= + callback;

window[callback] = function (data) {

    // it worked!

    console.log(data);

};

s.src = url;

document.body.appendChild(s);
