Interface fonts in Firefox and Thunderbird with KDE4

[James Amundson]

Hi,

Does anyone out there understand how Firefox and Thunderbird determine 
which fonts to use for their user interface, i.e., menus, etc? I have 
installed "GTK styles and Fonts" display settings module. It works fine 
for ordinary gtk and Gnome applications. However, Firefox and 
Thunderbird seem to have some more complex system for determining their 
system fonts. The only way I can get F & T to respect my font choice 
while using KDE4 is to
    (1) log in under Gnome,
    (2) change some font settings,
    (3) log out (without rebooting)
    (4) log in under KDE4.

Does anyone else have this problem? I'd love to report it as a bug, but 
I'm not even sure which component is the problem.
