title: SSRS in firefox not asking for credentials
body: <p>I have a 2012 SQL Server Reporting Server, I have various reports in it. When I access to the server via Chrome Browser (<a href="http://XX.XX.X.XX/Reports/Pages/Folder.aspx" rel="nofollow">http://XX.XX.X.XX/Reports/Pages/Folder.aspx</a>) ask me for credentials as normally, but when I access the same URL via Firefox it does not, it just only displays a blank page. It also asks authentication normally in IE.</p>
  
  <p>Some details:</p>
  
  <p>MAC OS X 10.9.4 
  Firefox version 32.0.3</p>
  
  <p>Does anyone have idea of what can be happening?
  Thanks for the time.</p>
  
  <p>EDIT: Firefox in windows is working correctly with the same version I have in MAC.</p>
  
  <p>EDIT: Updated to latest version of Firefox 33.0, it does not work.</p>
