By CSS 2, he means specifically CSS 2.1--which is supported by Firefox.

See http://www.w3.org/TR/CSS21/syndata.html#q6 , specifically the second 
bullet ("In CSS, identifiers (including element names, classes, and IDs 
in selectors) can contain only the characters [a-z0-9] and ISO 10646 
characters U+00A1 and higher, plus the hyphen (-) and the underscore (_).")

See, also, the entire thread at 
http://www.gossamer-threads.com/lists/mythtv/dev/255015#255015 , where I 
was corrected for saying that it seems to be supported by all versions 
of CSS, and the conversation about support in browsers.

I still think something else--i.e. browser cache, or perhaps some 
Firefox extension you've installed or some Firefox config you've set   
is forcing your browser into CSS 2.0 or CSS 1.0 format, or something--is 
causing issues for you.

It works perfectly for me on Firefox (1.0, 1.5, and 2.0, so far).
