Do I need a xorg.conf to use webfonts?

[Xn Nooby]

I installed FreeBSD 8.1, and the xorg package automatically detected
my video-card and monitor.  I did not have to create an xorg.conf
file.

If I want to webpages to look better in Firefox, I think I need to
install the "webfonts" package.  Section 5.5.2 of the Handbook seems
to say I need to modify my xorg.conf to use True Type fonts.

Do I need to create an xorg.conf to modify, or does the X server
automatically use new TTF fonts?
