All of this code has moved to polyfill.js

-  let messageQueue = [];
-  let maxMessageId = -1;
-  let loadHandler = (event) =>
-  {
-    if (event.data.type == "backgroundPageLoaded")
-    {
-      let queue = messageQueue;
-      messageQueue = null;
-      if (queue)
-      {
-        for (let message of queue)
-          backgroundFrame.contentWindow.postMessage(message, "*");
-      }
-      window.removeEventListener("message", loadHandler);
-    }
-  };
-  window.addEventListener("message", loadHandler);
-
-  /* Polyfills */
-
-  if (!("runtime" in chrome))
-    chrome.runtime = {};
-
-  function sendRawMessage(message)
-  {
-    if (messageQueue)
-      messageQueue.push(message);
-    else
-      backgroundFrame.contentWindow.postMessage(message, "*");
-  }
-
-  chrome.runtime.connect = () =>
-  {
-    sendRawMessage({type: "connect"});
-    return {onMessage: ext.onMessage};
-  };
-
-  chrome.runtime.sendMessage = (message, responseCallback) =>
-  {
-    let messageId = ++maxMessageId;
-
-    sendRawMessage({type: "message", messageId, payload: message});
-
-    if (responseCallback)
-    {
-      let callbackWrapper = event =>
-      {
-        if (event.data.type == "response" && event.data.messageId == messageId)
-        {
-          window.removeEventListener("message", callbackWrapper);
