Wordpress, troubles with Firefox


I’ve been working on a site using wordpress and I stumbled upon a problem. The site in question is: http://www.landgoedbeekzicht.nl/ and the problem only considers visitors using Firefox. When viewing the site with firefox the quickmenus, the blocks on the bottom, are placed on the right, while with Chrome or IE they’re shown correctly. Does anybody know what I did wrong?

Thanks in advance,

Try this:

.midrow {
    [color=blue]clear: both;  /* add me */[/color]

You will lose the background color behind the title, but it was incorrectly applied by .midrow anyway.

Apply it to div.logo instead, if desired.

BTW: Just offhand, I can see no reason to float the slider_wrap or the header.
