title: Chrome Extension. Onload Blur fails.
body: <p>I'm creating a Chrome Extension that blurs any textarea of a page when loading, but it doesn't work. Any ideas? Here's the code:</p>
  
  <p>Manifest.json:</p>
  
  <pre><code>{
  "name":"foo",
  "version":"1.0",
  "manifest_version":2,
  "description":"foo",
  "content_scripts":[{
       "matches":["http://*/*"],
       "js":["content.js", "jquery-1.8.3.min.js"]}]
   }
  </code></pre>
  
  <p>Content.js:</p>
  
  <pre><code>$(document).ready(function(){
  $("input").blur})
  </code></pre>
