Firefox has v-sync video playback issue

[jd]

The video playback on firefox has obvious v-sync issues, when videos playing like netflix or youtube etc, the video has a horizontal band of mismatch, likely a v sync problem, especially when the camera is moving fast.  Chrome or edge were a lot better handling the issue.  The main reason I'm using firefox is its better privacy protection, but I have to switch to chrome for viewing videos.  This needs to be fixed.

seems to be hardware acceleration issue, turning on fixed it.

It would be nice to get this issue resolved without having to turn on hardware acceleration.

What does number 5 even do when I change it?

Also the screen tearing still exists, and I am not enabling hardware acceleration, I shouldn't need to, to prevent something like screen tearing, it should just respect my vsync option I have set in control panel.

Why did you link to some dubai milk site?

This issue is also a thing when just scrolling some web pages, not just watching a video.
