title: Firefox does not load any files (css, js, images)
body: <p>i have a weired problem. The Firefox is not loading the css files while IE and Chrome does. 
  Yes, i've cleared the cache a few times. The encoding is correct (utf8) and the file is valid (w3c). Even an older version of firefox does not solve the problem.</p>
  
  <p>I should at least see the call for the css file in the networktab of firebug. There's only one call for the page i want to visit.</p>
  
  <p>Even the imagefile i've added to the page is'nt loaded...</p>
  
  <p>What is wrong?</p>
