Firefox menu font too big

Hello,

I have the following problem with Firefox 2.0: The font of the menu and
the size of input boxes in webpages are to big. Firefox 1.5 had a dpi
setting in the preferences with which I could correct this. But in
Firefox 2.0 this setting is gone. 

I use XFCE as window manager. The font size settings of XFCE do not
apply to the size of the font of the menu bar.

Does anybody have an idea how to fix this?

Regards,

Markus
