Feed not showing up properly in FireFox
 

I'm trying to get the proper feed address so that I can update my feedburner details. When I view the feed in Internet Explorer, it shows up just fine. However, when I try to view it in Firefox, I get this error:
This XML file does not appear to have any style information associated with it. The document tree is shown below.

Here's the feed address that I'm using: http://www.rundpinne.com/feed

If I change my feedburner account to that link, are my email subscribers going to get a funky email every night, or will they get the actual posts?
