title: Load a javascript resource from an external source, when it's blocked with a 403 status
body: <p>For some reason my ISP is blocking the following URL:</p>
  
  <pre><code>http://assets.tumblr.com/javascript/prototype_and_effects.js
  </code></pre>
  
  <p>Chrome console states:</p>
  
  <pre><code>Failed to load resource: the server responded with a status of 403 (URLBlocked)
  </code></pre>
  
  <p>The result is I can't use <em>Tumblr</em> properly because many functions depend on this script. I have already contacted my ISP and asked them to stop blocking this URL, but meanwhile I would like to do something about it.</p>
  
  <p>How can I load this resource externally? It could be a bookmarklet solution, userscript/Greasemonkey or any other thing you can think of.</p>
