I am seeing this exact problem with Ubuntu 14.10. I began with a clean installation of ubuntu-desktop and later installed ubuntu-gnome-desktop and kubuntu-desktop. After removing all but ubuntu-desktop, I am unable to restore Firefox and Thunderbird's original font. I've tried removing configuration files in ~ but it doesn't seem to make a difference. Also, creating a new Firefox profile didn't help.
