video in Firefox not streaming

[Anil Felipe Duggirala]

hello,

I am sorry to ask this here but am wondering why the last couple of 
times I have installed Fedora 32 workstation, video playback in Firefox 
is not working out of the box for some sites. So I can play videos on 
youtube, but for example, trying to play a video in cnn.com ("something 
went wrong during native playback") does not work, or playing some video 
from Twitter("media could not be played") does not work either.

Am I missing the Flash Player? What am I missing here?

thank you,
