Firefox fonts

Hi,
I’m using openSUSE 11.2 gnome, but with some kde apps. Font settings under gnome are set to use subpixel rendering and full hinting, but with kde apps, fonts look greather with hinting set to slight. It is ok, can be set in systemsettings.

Now comes firefox: when I set in systemsettings (kde control center) slight hinting, fonts in firefox tab and bookmark bar became huge. When I set hinting to full in kde control center, the fonts in webpages became ugly.

This is happening since I installed KDE (kde 4.4). Before that, everything was ok, fonts in firefox looked great. What can I do with this?

Thank you!
