Помогите реализовать отображение для аддона к mozilla.

[Ingiborn]

Здравствуйте.
Есть шмоток кода, отвечающий за выборку стран, помогите реализовать выборку не по ротации, а рандомно.
Спасибо!

switchCountry: function () {
        var countries, menu, context_menu;
        switch (countryTool.prefManager.getCharPref("extensions.countrytool.country_type")) {
        countryTool.clearAllCountriesStyles();
        var menuitem_country = menu.childNodes[countryTool.currentRotateCountryIndex];
        var context_menuitem_country = context_menu.childNodes[countryTool.currentRotateCountryIndex];
        menuitem_country.setAttribute("checked", true);
        context_menuitem_country.setAttribute("checked", true);
        menuitem_country.setAttribute("style", "font-weight: bold");
        context_menuitem_country.setAttribute("style", "font-weight: bold");
        if (menuitem_country.hasChildNodes()) countryTool.selectedCountryFlag = menuitem_country.childNodes[0].getAttribute("src");
        else countryTool.selectedCountryFlag = "";
        var country_info = menuitem_country.getAttribute('value').split(",");
        countryTool.countryChanged(country_info[0].split(":"));
        countryTool.selectedCountryCity = (country_info[1] == "undefined") ? "" : country_info[1];
        if (country_info[2] != "undefined") countryTool.selectedCountryCity += "," + country_info[2];
        var labelText = menuitem_country.getAttribute('label');
        var index = labelText.substring(0, labelText.indexOf("."));
        var stringbundle = document.getElementById("countrytool-strings");
        countryTool.showPopup("country", stringbundle.getString("currentcountryindex") + ": " + index);
        countryTool.currentRotateCountryIndex++;
        if (countryTool.currentRotateCountryIndex == countries.length || countries.length == 0) countryTool.currentRotateCountryIndex = 0
    },

Нет не у кого мыслей? очень надо..

Всё ещё интересует ответ на вопрос!
Не могу разобраться, работу дальше продолжить не могу..
Как я понимаю за ротацию отвечают последние 2 строки, что использовать?
math.random?

    },

Помогите!
