FreeBSD 8.0 and KDE Fonts

[What you get is Not what you see]

On 8.0 with KDE 4.3.1 package installed I have problems with Firefox fonts.
Though I installed URW and freetype fonts according to handbook and
declared them on xorg.conf,
Firefox 3.5.4 cant display some pages properly,ie text is not
displayed. So that must be a problem with fonts,
because those pages are displayed (well) with Konqueror.
What would be the resolution?
