The failing Firefox in Rawhide is 46.0.1. It has a Firefox 41.0.2 installed from and it *works*. I have a home machine which does not run Fedora, which was running in such a configuration (only one font family) for many years. Other X apps work fine: gedit, xfce4-terminal, entire xfce4 session runs okay.įirefox and Thunderbird will start working fine if you add, for example, DejaVu Mono fonts to /usr/app/Xfonts/ (you can use attached Xfonts_ archive to try it).

It is set up to pick up only fonts from /usr/app/Xfonts/* * save and replace /etc/fonts/nf with attached nf This archive contains only 'misc-fixed' font files, nothing else I strip my machine of fonts by 'rpm -e -nodep''ing them, but you can reproduce this bug by simply temporarily replacing fontconfig configuration so that it does not find your fonts: Looks like it somehow fails to find a 'sans-serif' font, even though fc-match does work:

#!!!

Mozilla firefox 41.0.2 bad
