When watching a HDR video on Firefox on Mac (in this case, a Mac Mini M4 running Sequoia) - freshly installed, connected to an AOC QHD HDR monitor via USB-C->Displayport cable, the video appears overexposed with large patches of white making the video unwatchable. This applies to all HDR video on Youtube.

Watching the same video on Safari presents no such issues - HDR video plays as expected.
