Since the latest MF update in August 2019, Youtube videos no longer play (they open and then stop after a few seconds). They play on other browers.

Since the latest MF update in August 2019, I have been having trouble loading Youtube videos. I can access the video itself, but then it freezes after a few seconds. I am not able to refresh the page nor does the enlarge screen button work. I have already 1) removed cookies and cache, clearing all recent history. 2) I have also tried entering Firefox in safe mode and the same problem occurs. I also tried adding a Youtube Flash player as an add-on on Firefox, but this did not work. Youtube videos play fine on both Internet Explorer and Chrome browsers.

I have Shockwave Flash 32.0 r0 as one of my plugins. Could this be causing the problem?

Youtube currently uses the HTML5 player.
