I just don't understand why CSS acts super picky. If you use w3schools "Try-it" editor, it's so hit and miss when it is and isn't going to work. Right now I'm focusing on links (a:link, visited, hover, active) and I'm unable to get it all to behave correctly. I know Firefox disabled this functionality because of a history leak, but that was 2 years ago (and my layout.css.visited_links_enabled is set to "True"). Here is the "Try-it" editor: http://www.w3schools.com/css/tryit.asp?filename=trycss_link If I copy and paste the color code from a:hover, it doesn't change. As always, thanks in advance. P.S. I'm using Firefox 11.
