The following is a jQuery solution to popup blocker checking. It has been tested in FF (v11), Safari (v6), Chrome (v23.0.127.95) & IE (v7 & v9).

var popupBlockerChecker = {
    check: function(popup_window){
        var _scope = this;
        if (popup_window) {
            if(/chrome/.test(navigator.userAgent.toLowerCase())){
                setTimeout(function () {
                    _scope._is_popup_blocked(_scope, popup_window);
                 },200);
            }else{
                popup_window.onload = function () {
                    _scope._is_popup_blocked(_scope, popup_window);
                };
            }
        }else{
            _scope._displayError();
        }
    },
    _is_popup_blocked: function(scope, popup_window){
        if ((popup_window.innerHeight > 0)==false){ scope._displayError(); }
    },
    _displayError: function(){
        alert("Popup Blocker is enabled! Please add this site to your exception list.");
    }
};

Usage:-

var popup = window.open("http://www.google.co.in", '_blank');
popupBlockerChecker.check(popup);

Hope it will help.
