Yep I think they all work. This example from the CSS 2 spec works (which I think does not in Mozilla):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN">
<TITLE>Creating a list with markers</TITLE>
content: counter(mycounter, lower-roman) ".";
<LI> This is the first item.
<LI> This is the second item.
<LI> This is the third item.
I think the page breaks work fine too. They have site navigation bars, alternate style sheets, and a bunch of other style implemented too now. I find it does crash from time to time, but it's really good apart from that.
