+(function()

I presume that it won't be possible to expand the additional text when JS is
disabled?

+{
+  var visibleTab;
+  var container;
+  
+  window.toggleMore = function()
+  {
+    if (container.className == "hidden")
+      container.className = visibleTab || getDefaultTab();
+    else
+      container.className = "hidden";
+  }
+  
+  window.showTab = function(button)
+  {
+    var id = button.id.substr(5);
+    container.className = id;
+    visibleTab = id;
+  }
+  
+  function getDefaultTab()
+  {
+    var content = document.getElementById("content");
+    var ua = content.className.match(/ua\-([^\s]+)/);
+    visibleTab = ua && ua[1] || "firefox";
+    return visibleTab;
+  }
+  
+  function init()
+  {
+    container = document.getElementById("more-container");
+  }
+  
+  init();
+})();
