The following sites all have video playback issues for me: HBO Go, Netflix, Showtime Anytime, Hulu, Xfinity. - HBO freezes every for several seconds every 15 seconds or so. When it does this it repeats audio from the moment where it began freezing to where it stops freezing. Rinse and repeat. - Netflix, Showtime, and Hulu flicker aggressively. The behavior is persistent and unwatchable. - Xfinity is laggy, as if it's playing only every second frame.
macOS 10.13.6, Firefox 63.
I have done the following troubleshooting:
Start in Safe Mode. Check Adobe for Flash for updates. Changed Flash's settings / disabled hardware acceleration Tried turning on and off Automatic Graphics Switching in macOS system preferences.
None of the above have any impact, no matter what I do I cannot watch any TV in Firefox. I have experienced this in 10.11 and 10.12 with earlier versions of Firefox as well, for the past few years I cannot watch any streaming media in Firefox, forcing me back to Chrome every time... (This includes two MacBooks, the current one being brand new.)
Disappointing to say the very least as FF does run super fast, but since it's useless for watching TV/movies in my browser I just stick with Chrome...
