title: Make a Retro Neko Cat Browser Extension
body: <p>I have Javascrpit for the Neko Cat and it works when you load it in a web browser. Please see below:</p>
  <p><em>neko_cat.html</em></p>
  <pre><code>&lt;script&gt;NekoType=&quot;socks&quot;&lt;/script&gt;
  &lt;h1 id=nl&gt;&lt;script src=&quot;https://webneko.net/n20171213.js&quot;&gt;&lt;/script&gt;&lt;a href=&quot;https://webneko.net&quot;&gt;Neko&lt;/a&gt;&lt;/h1&gt;
  </code></pre>
  <p>I would like to create a firefox web extension so this script is loaded on every web page.</p>
  <p>I have looked at the following but I can't get it to work.</p>
  <p><em>manifest.json</em></p>
  <pre><code>{
    &quot;manifest_version&quot;: 2,
    &quot;name&quot;: &quot;Neko Cat&quot;,
    &quot;version&quot;: &quot;1.0&quot;,
    &quot;description&quot;: &quot;&quot;,
    &quot;content_scripts&quot;: [
      {
        &quot;matches&quot;: [&quot;*://*.mozilla.org/*&quot;],
        &quot;js&quot;: [&quot;neko_cat.js&quot;] //code put ino a js file.
      }
    ] 
  }
  </code></pre>
  <p>Any ideas on how to do this?</p>
  <p>Thanks.</p>
