Don't recommend this old setting. If you need GPU acceleration, force enable WebRender support in Firefox (gfx.webrender.all=1). Making web pages render with GPU support will barely help video decoding if at all though. For this to work well you need to tap into your hardware video decoder, which none of these settings achieve.
