Either it is a bug in Firefox 3.5 RC or the mime-type provided is wrong. It just renders like text, and not like an RSS-feed I can just click to subscribe to.

Either it is a bug in Firefox 3.5 RC or the mime-type provided is wrong. It just renders like text, and not like an RSS-feed I can just click to subscribe to. Since RSS feeds seems to work on other sites, I'll assume the problem is with the feed. Correct mimetype should be application/rss+xml.
