Firefox does not support full-range video at all, even with software decoding. See bug ticket: https://bugzilla.mozilla.org/show_bug.cgi?id=1459526 https://bugzilla.mozilla.org/show_bug.cgi?id=1459526 Or just test this: https://bug1459526.bmoattachments.org/attachment.cgi?id=8984703 https://bug1459526.bmoattachments.org/attachment.cgi?id=8984... Firefox's video support in general is pretty poor compared to Chrome. It doesn't support RGB or 4:4:4/4:2:2 YUV video either. >here is the workaround I knew that bug too, but that's a different story. That is about Firefox having problem to playback limited range video properly with nV graphic card (and it's partially nVidia's fault than Firefox). Chrome used to have that bug too, but they have fixed it. (Firefox team on the other hand, didn't plan to fix it for Win7 at least: https://bugzilla.mozilla.org/show_bug.cgi?id=1410693#c1 https://bugzilla.mozilla.org/show_bug.cgi?id=1410693#c1 ).
