Browser / Version: Firefox 126.0
Operating System: Mac OS X 10.15
Tested Another Browser: Yes Other
Problem type: Video or audio doesn't play
Description: The video or audio does not play
Steps to Reproduce:
Most of the YouTube videos that are using 1080p Premium and 4K resolutions either will not play with a spinning wheel graphic or plays for a moment then pauses with the spinning wheel. Refreshing the page didn't work. Clicking just before or after the trouble spot on the timeline also didn't work. I am also seeing the same issue on some videos with the 1440p resolution where in the past videos would play fine at that resolution. All of these problems went away when I set the "gfx.webrender.compositor" setting to "false" in about:config. This issue came up in the previous 125.0 release, and in prior releases I didn't experience this issue. I have tested the same videos in Vivaldi and Safari and there were no playback issues in those higher resolutions.
