Well I finally got around to validating my feeds. They do in fact validate, but I’m still getting the document tree intermittently on Firefox 3.0.3 for Mac OSX.

<p>If you haven’t already been to stanandjess.com, there is currently a place-holder cartoon on the site. Rest assured, the real cartoon is coming soon and will be updating weekly. I’ll be sure to let you all know when I roll out the first strips.
As I mentioned before, if I page back on the browser and hit the feed again, it usually works.
Is it possible this is a Firefox issue?
