Facebook分享按钮自行调整尺寸

Question

我的Facebook分享按钮工作完美，直到几天前它开始重新调整自身并拒绝打开，任何有关导致此问题的线索？\

这是弹出窗口的js脚本

function fbShare(url, title, descr, image, winWidth, winHeight) {
    var winTop = (screen.height / 2) - (winHeight / 2);
    var winLeft = (screen.width / 2) - (winWidth / 2);
    window.open('http://www.facebook.com/sharer.php?s=100&p[title]=' + title + '&p[summary]=' + descr + '&p[url]=' + url + '&p[images][0]=' + image, 'sharer', 'top=' + winTop + ',left=' + winLeft + ',toolbar=0,status=0,width=' + winWidth + ',height=' + winHeight);
}

这里是链接

<a href="javascript:fbShare('http://dundaah.com/docs/tue.html', 'Fb Share', 'Facebook share popup', 'http://goo.gl/dS52U', 520, 350)" class="button">Share</a>

如果这看起来很熟悉，我的原因是jsfiddle
