The Firefox is executed within the Xorg - X server.
So you can start from there,
- Xorg module for video card
- Mesa-based DRI module
Down the rabbit hole,
- Kernel video module
Xorg ati video module
https://admin.fedoraproject.org/pkgdb/acls/bugs/xorg-x11-drv-ati
Xorg Intel video module
https://admin.fedoraproject.org/pkgdb/acls/bugs/xorg-x11-drv-intel
Xorg nouveau video module
https://admin.fedoraproject.org/pkgdb/acls/bugs/xorg-x11-drv-nouveau
Mesa-based DRI modules
https://admin.fedoraproject.org/pkgdb/acls/bugs/mesa
For testing purposes you can temporarily switch to:
Xorg modesetting video module - basic modesetting fallback module
https://admin.fedoraproject.org/pkgdb/acls/bugs/xorg-x11-drv-modesetting
i.e.
$ cat /etc/X11/xorg.conf
Section "Device"
Identifier "video0"
Driver "modesetting"
EndSection
Check what's happening with:
$ cat /var/log/Xorg.0.log
