Why is FireFox 57 (and previous) on Linux (Fedora) unable to play videos from Pluralsight?
On Fedora 27 (and earlier versions) I am unable to play videos from Pluralsight.com. I recently installed OpenH264 codec, but enabling it does not solve the issue.

The Pluralsight uses a HTML5 video player. Not sure of exact packages for your Linux distro but make sure you have say FFmpeg installed and then you can check if you fully support HTML5 player at say https://www.youtube.com/html5/
The Cisco H264 Plugin has nothing to do with the HTML5 player or playing mp4 video. It is for Web RTC. https://blog.mozilla.org/blog/2013/10/30/video-interoperability-on-the-web-gets-a-boost-from-ciscos-h-264-codec/

Can you test using binaries from Mozilla. Check out, https://ftp.mozilla.org/pub/firefox/releases/57.0/linux-x86_64/

Thank you very much, that did the trick. Don't know why I couldn't find that information on my own, but now I know.
