As described in the w3c CSS specification:
http://www.w3.org/TR/CSS2/generate.html#counters

If I've done the CSS right, the sample code in the steps to "reproduce" section below, the html should produce numbered headings and subheadings.  It does this with Opera, but not Firefox.

Sorry if I've made a mistake or misunderstood the specification; but in case this really is a bug, I wanted to report it to help improve Firefox.

Reproducible: Always

Do you mean bug 288946 ?
You need to put the counter-resets on the element rather than on its :before pseudo-element.  See http://dbaron.org/cdi-req/ for an example.  If the counter-reset is on the :before, the scope it establishes ends at the end of the element.
