title: How can I use a text file as a database in javascript? (Firefox addon)
body: <p>I have a text file like this:</p>
  
  <pre><code>settings:value
  data:integer:boolean
  data:integer:boolean
  data:integer:boolean
  data:integer:boolean
  ...
  </code></pre>
  
  <p>I need CRUD operations over this text file using javascript.
  <strong>This file is in the same js file's directory.</strong></p>
  
  <p><strong>EDIT</strong> after some comments: 
  This is for a <strong>Firefox addon</strong>. Maybe we can count with more privileges?</p>
