gtk-chtheme - effecting Firefox fonts

[Joseph_sys]

I wanted to change evolution fonts (make it slightly bigger) so I found recommendation to use: gtk-chtheme it did worked on evolution folder index but it as well effected Firefox fonts.

Is the better program to adjust evolution fonts only?
I'm using KDE.

Both evolution and firefox are gtk+ applications. gtk-chtheme is changing the gtk font, thus it is changing it for all gtk+ applications. I don't think you have any other alternatives. (other than sticking with KDE apps... )
