If you really need to test the HTML5 output in Firefox (I can't imagine why) you could activate it through "about:config" and setting html5.enable to true. Remember that they didn't switch it off for nothing. For real world work you will need CSS, so I suggest you get stuck in with that as well.

Firefox 3.6 doesn't support HTML 5 sectioning elements yet. You will have to manually style the tags to be block level:

article, aside, canvas, details,

hgroup, nav, section, summary, video {
    display: block;
}

You won't need the HTML shim, however; that's just for IE.
