I'm trying to learn XSLT. I've run into an immediate problem, which is that the version of Firefox I'm running -- 2.0.0.3 -- just gives me a blank, dark grey screen. This is simple "hello world" XML/XSLT but afaik it's correct and should render a couple of lines of text.

I've tried Googling the problem and I can't understand what I read. Sorry to be such a noob, but does anyone have a simple explanation for a noob and, hopefully, a solution?
