title: Chrome Extension: How to solve "Not allowed to load local resource" error upon content script injection
body: <p>I tried to inject jQuery to content page to make easy access to DOM elements.<br>
  The code was something like below</p>
  
  <pre><code>chrome.tabs.executeScript(tabId, { file: "jquery.min.js"} ,function(){
      chrome.tabs.executeScript(tabId, { file: myOwnScript.js});}
  ); 
  </code></pre>
  
  <p>It was all fine on Windows, but on Ubuntu, in content page window, I always get console error message saying<br>
  "Not allowed to load local resource: file:///****/jquery.min.map"</p>
  
  <p>I noted it was talking about *.<strong>map</strong> but not *.<strong>js</strong></p>
  
  <p>There are some more mysteies:<br>
  1. There is no error message on <em>myOwnScript.js</em><br>
  2. My extension works well even though this message keeps showing at each page load.</p>
  
  <p>I made plenty searches on Google but didn't find similar case.</p>
  
  <p>My questions is,<br>
  1. What is the reason of such error?<br>
  2. Should I take it as a serious error?</p>
  
  <p>My enviroment is as below<br>
  OS  : Ubuntu 14.04, with LXDE desktop<br>
  Chrome  : 34.0.1847.132<br>
  (Didn't try other configurations because I am not that good at customizing Linux :)</p>
