Though can you just out of curiosity test with hardware acceleration turned off in settings and see if it makes it work.
Otherwise you can also try force enabling the hardware compositing by entering the address and then search for
layers.acceleration.force-enabled aswell as layers.offmainthreadcomposition.enabled make sure both are set to true.
Finally start firefox by executing the following in a terminal (close existing windows beforehand)
Hope that works for you. If it does you can write the variable into the environment file so it stays put on every reboot. You can do so by executing
