Investigate incompatability with OpenH264 in Firefox

[clone1018]

Seemingly related to Glimesh/glimesh.tv#907 -- another user had an issue with the generic Firefox package maintained by various package maintainers. Turned out to be the same issues with a missing H264 decoder.

It does appear Firefox comes with an OpenH264 codec, but for some reason it doesn't render our streams?

Interestingly enough the Waveguide backend did print out unable to start track, codec is not supported by remote

I personally resolved this by installing my distro's Mozilla version of OpenH264, enabling it in Firefox, then restarting Firefox.

Issue seems to be related to Firefox no longer prepackaging OpenH264.
