有没有可以复制当前标签页标题和网址和扩展？

(function()
{
    window.ucjs_copyTabInfo = function(aAsBBCode)
    {
        var tab = document.popupNode;
        var surl = gBrowser.getBrowserForTab(tab).contentWindow.location.href;
        var txt = aAsBBCode ?
            '[url="' + surl + '"]' + tab.label + '[/url]' :
            tab.label + "\n" + surl;
        var clipboard = Components.classes["@mozilla.org/widget/clipboardhelper;1"]
                        .getService(Components.interfaces.nsIClipboardHelper);
        clipboard.copyString(txt);
    };
    var menuitem1 = document.createElement("menuitem");
    menuitem1.setAttribute("label", "Copy Title + URL");
    menuitem1.setAttribute("oncommand", "ucjs_copyTabInfo(false);");
    var menuitem2 = document.createElement("menuitem");
    menuitem2.setAttribute("label", "Copy Title + URL (BBCode)");
    menuitem2.setAttribute("oncommand", "ucjs_copyTabInfo(true);");
    setTimeout(function()
    {
        gBrowser.mStrip.childNodes[1].appendChild(document.createElement("menuseparator"));
        gBrowser.mStrip.childNodes[1].appendChild(menuitem1);
        gBrowser.mStrip.childNodes[1].appendChild(menuitem2);
    }, 0);
})();
