Fedora 27 Firefox does. Fedora 28 Firefox does not.
Yes, it does. I thought of a reason why this might be true. I had
been running a version of rawhide that was updated for many releases,
and decided to stop at F28. I probably carried over into F28 from those
earlier releases whatever is causing your problem, especially if yours
was a new install.
To Todd's point, I noticed in my updates today that rpmfusion had ffmpeg
updates, so that might solve your problem.
