[Discuss] Can't play Facebook videos in Firefox

[cra at WPI.EDU (Chuck Anderson)]

Youtube video works fine with Fedora 28 Firefox on my system.  I do
have rpmfusion-free and rpmfusion-nonfree repos enabled, along with a
bunch of packages--not sure which ones you need exactly.  After
enabling the rpmfusion repos, I usually do this:

>sudo dnf --exclude='*debug* --exclude='*devel* install gstreamer1* audacious-plugin* mpg123\* xmp-plugin*

This is what I have:

>rpm -qa gstreamer\* audacious-plugin\* mpg123\* xmp-plugin\* | sort
