title: can i be notified of cookie changes in client side javascript
body: <p>Can I somehow follow changes to cookies (for my domain) in my client side javascript. For example a function that gets called if a cookie gets changed , deleted or added</p>
  
  <p>In order of preference</p>
  
  <ul>
  <li>standard cross browser   </li>
  <li>cross browser</li>
  <li>browser specific</li>
  <li>extension / plugin</li>
  </ul>
  
  <p>Why? because cookies I depend on in window / tab #1 can get changed in window / tab #2.</p>
  
  <p>I found out that chrome allows extensions to be notified of cookies changes. But thats my least favorite option</p>
