I'm running RHEL 6.5 x86-64, fully updated as of today and KDE.
I noticed that the fonts used by Thunderbird and Firefox look really poor even though I have forced 96 DPI in "System Settings => Appearance => Fonts".
Everything else looks good so I believe this to be a GTK issue.
On a SUSE system I have running KDE, under "System Settings => Appearance" there is also "GTK Styles and Fonts" but this is not present under RHEL.
How can add this?
If not possible, how can I control/fix the fonts used by Thunderbird/Firefox?
Many thanks for your time!
