From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0.0) Gecko/20020530
BuildID:    2002053012

HTML uses CSS stylesheet that defines 
A.defined:visited { color: purple } and A:active { color: lime }.
The HTML contains an anchor with class="defined".  Only the first
activation results in a lime color.


Reproducible: Always
Steps to Reproduce:
1.Navigate to view the attached HTML.
2.Edit=>Preferences menu item.
3.In the Preferences dialog, click on category Navigator->History.
4.In Preferences, click on the Clear History button.
5.View=>Reload menu item.
6.Click on 'Anchor class="defined"'.  Color will change from
  red to lime to red again.
7.View=>Reload.  Color of the anchor will change to purple.
8.Click on 'Anchor class="defined"' again.  Color will not change
  to lime as it should.

Actual Results:  The anchor marked 'Anchor class="defined"' will only change it's
color to lime when it is active the first time.

Expected Results:  The anchor marked 'Anchor class="defined"' should change it's
color to lime every time it is activated.

Mozilla is behaving correctly here. The order of definitions is only used as a 
tie breaker for equally specific rules. 

http://www.w3.org/TR/REC-CSS2/cascade.html#cascading-order

"if two rules have the same weight, origin and specificity, the latter 
specified wins". This is not the case here: including the class makes the rule 
more specific so it wins over the later rule.

Yes, it's invalid, not worksforme, and it also belongs in the style system
component.
