RSS Problem

I seem to be having an error with my RSS feed, http://www.stevepeer.net. Using Green Shade theme, WP 2.3.1. When the RSS link is clicked in Firefox I’m taken to an orange page, and nothing is displayed. The comments RSS displays as it should. In IE I get a page of code when the RSS link is clicked. Every other site I’ve gone to give a list of readers after an RSS link is clicked. What’s the deal? I’m an RSS idiot, but I think something is wrong.
