请教 鼠标手势（firegestures）添加 返回上次选中标签 的脚本

请问鼠标手势（firegestures）中添加返回上次选中标签的脚本是什么？也可以是tab mix plus 中“ctrl-tab 以最近被浏览的顺序切换标签页”的脚本
谢了先！！！

if ("tabFocusManager" in FireGestures == false) {
  // init tab focus manager
  FireGestures.tabFocusManager = {
    _tabHistory: [],
    focusLastSelectedTab: function() {
      var currentPanel = gBrowser.mCurrentTab.getAttribute("linkedpanel");
      while (this._tabHistory.length > 2) {
        var panel = this._tabHistory.pop();
        if (panel == currentPanel)
          continue;
        var tab = document.getAnonymousElementByAttribute(gBrowser, "linkedpanel", panel);
        if (!tab)
          continue;
        gBrowser.selectedTab = tab;
        break;
      }
    },
    handleEvent: function(event) {
      this._tabHistory.push(event.target.getAttribute("linkedpanel"));
      if (this._tabHistory.length > 32)
        this._tabHistory.shift();
    },
  };
  gBrowser.mTabContainer.addEventListener("TabSelect", FireGestures.tabFocusManager, false);
}

FireGestures.tabFocusManager.focusLastSelectedTab();

saga2008：

if ("tabFocusManager" in FireGestures == false) {
  // init tab focus manager
  FireGestures.tabFocusManager = {
    _tabHistory: [],
    focusLastSelectedTab: function() {
      var currentPanel = gBrowser.mCurrentTab.getAttribute("linkedpanel");
      while (this._tabHistory.length > 2) {
        var panel = this._tabHistory.pop();
        if (panel == currentPanel)
          continue;
        var tab = document.getAnonymousElementByAttribute(gBrowser, "linkedpanel", panel);
        if (!tab)
          continue;
        gBrowser.selectedTab = tab;
        break;
      }
    },
    handleEvent: function(event) {
      this._tabHistory.push(event.target.getAttribute("linkedpanel"));
      if (this._tabHistory.length > 32)
        this._tabHistory.shift();
    },
  };
  gBrowser.mTabContainer.addEventListener("TabSelect", FireGestures.tabFocusManager, false);
}

FireGestures.tabFocusManager.focusLastSelectedTab();
