I am running an iMac with Yosemite software, 4gigs of RAM and the FireFox 57 up-dated itself like it has many times before. NOW, I am totally unable to play any video from YouTube, no movies either. Seems there is some concern about HTML5. YouTube says, "your browser currently does not recognize any of the video formats available". Thats YouTube talking to me about your funky browser

All those boxes are checked. I rolled the FireFox edition back to 54 from 57 and the browser icon stayed the same. The browser did roll back but is still unable to play any video
