RSS feeds articles not showing in mozilla firefox only

Question

I followed the following tutorial to create a RSS FEED:

http://ci-codeigniter.blogspot.com/2011/12/how-to-build-rss-20-feed-with.html

Everything is good in all browsers except mozilla firefox.

http://lowcostseo.co/feeds

is the feed.

Im not sure what went wrong. Does anyone knows whats wrong with Firefox?

Thanks. -------------EDITS------------------------

Whats Happening: If you check http://lowcostseo.co/feeds in chrome all is good i think but if you check it on mozilla you'll find that there no articles showing but if you check the the source code there are articles. So basically firefox is not showing articles which is present in source code.

Whats Expected: The articles needs to be shown in firefox RSS FEED at http://lowcostseo.co/feeds

Your feed is not valid, so you should not really expect any reader to do a consistent good job at displaying it.

The most obvious problem is that you do not close <link> element in your <item> elements... You should really check the validator and make sure your feed is valid before anything else.
