After upgrading to Mozilla 1.3, I've seen major CSS2 functionality loss. :hover
(dynamic pseudo-class) doesn't work after universal class selectors
(.classname:hover), where it worked in Mozilla 1.2.1. Still it works in
TAGNAME:hover (see http://mithgol.pp.ru/Mozilla/hoverbug.htm for test case).

All that makes me greatly upset. Probably we'll need Mozilla 1.3.1 really soon,
since several CSS2 menus are lost. Imagine .classname:hover { visiblity: ... };

Reproducible: Always

Steps to Reproduce:
1. Enter http://mithgol.pp.ru/Mozilla/hoverbug.htm in location field.
2. Load the page, follow the instructions.
3. Note that Mozilla 1.3 and 1.2.1 behave differetly.

Actual Results:  
Class .test:hover (see page source) doesn't work in Mozilla 1.3. A major feature
is broken; I'll set bug priority to Major.

Expected Results:  
Class .test:hover should work as in Mozilla 1.2.1, according to W3C
specification docs.

Tested under Win2000 and Win98, the same results.

I'm not completely sure that component is "Style System"; check it for yourself
also.
This was done intentionally, but in quirks mode only.  See bug 169078.  (It was
done because allowing this breaks a bunch of web pages that expect :hover to
apply only to links.)

If your page has a doctype that puts the browser into standards mode (see
http://mozilla.org/docs/web-developer/quirks/ ), then you won't have to deal
with these quirks.

Hmm...

You could at least mention it in your quirklist at
http://mozilla.org/docs/web-developer/quirks/quirklist.html - it's "Last
modified August 20, 2002", that's really old.

Your advice sounds really funny, my documents never validate under strict
validators, that's why I never used any !DOCTYPE, so what am I forced to do with
this quirk? To invent my own doctype?
You could just add "<!DOCTYPE html>"
Verified.  If your page is tag soup, it gets treated as tag soup (and you can
validate to Transitional and still have a doctype, you know...)

I think we can probably remove this quirk; WebKit doesn't have it.  (Or do they have a different variation of it?)

I cleaned up the edit here:

And added a note on Firefox 6 for developers. Thanks!
