title: "The stylesheet was not loaded because its MIME type, "text/html" is not "text/css"
body: <p>I have a javascript application and when I run it on firefox I am getting the following erro on the console:</p>
  
  <blockquote>
    <p>"The stylesheet was not loaded because
    its MIME type, "text/html" is not
    "text/css".</p>
  </blockquote>
  
  <p>DumbStuck!!</p>
  
  <p>EDIT:
  Note that it tells that "The stylesheet ABCD..."
  But ABCD is actually an HTML file.</p>
  
  <p>Edit (<strong>ANSWER</strong>) : Actually I had wrongly put <code>href=""</code>, and hence the html file was refenecing itself as the CSS. Mozilla had the similar bug <a href="http://www.mozdev.org/pipermail/project_owners/2008-January/010830.html" rel="noreferrer">once</a>, and it is from there I got the answer. But everyone's else answers helped me too. Thanks.</p>
