title: Chrome Extension Persistent
body: <p>I am trying to learn about chrome extension development. </p>
  
  <p>There I saw something like this manifest.json</p>
  
  <pre><code> "background" : {
        "scripts": ["Scripts/event.js"],
        "persistent": false
      }, 
  </code></pre>
  
  <p>Here, i am unable to understand what does  <code>"persistent": false</code> means, According to my very vague understanding, I think it deals wether the background page should run in background at all times or not. </p>
  
  <p>So If <strong>persistent is true,</strong> It will run even when we are working on tabs? and if it is false, it will stop it won't stop the moment we leave the browser? </p>
