title: Find original url of links rather than the tracking url from google, facebook etc
body: <p>I am making a chrome extension for pdf links</p>
  
  <pre><code>function getD(info, tab)
  {
     var url = info.srcUrl;
     var sb = "http://www.abcfadsds.com/?url="+info.linkUrl;
     chrome.tabs.create({"url":sb});
  }
  </code></pre>
  
  <p>Now this works for most links but if a right click a link on google / facebook
  the url generated is something like</p>
  
  <pre><code>http://www.google.co.in/url?sa=t&amp;rct=j&amp;q=pdf&amp;source=web&amp;cd......................
  </code></pre>
  
  <p>how do i obtain the original URL??</p>
