This may be a recent Firefox development, and it might not be available in ‘Windows’ or ‘OSX’. Unless your profile is messed up, or your firefox didn’t include the DAV1D Decoder, or your firefox is old – allowing firefox and youtube to use AV1, *without* degrading into a lesser video codec, seems to be WAY better. (Stuttering was visible in Chromium with full-screen layout on a 4K screen, there were no such artifacts on Firefox.) Why? AV1 uses less bandwidth than VP9, vastly less than VP8 or H.264 – so the same caching size can hold more seconds (or portions of seconds) of video, than it can with less efficient protocols.

I SWAG that these preferences cause YouTube to use AV1 (and Opus audio), with the dav1d video decoder.ĬPU Utilization, playing an HD video, is SMALLER than Google Chromium (~10% versus ~13%) and it also stutters less. Using Firefox 74 on Linux, versus Chrome 80: This version of Firefox defaults to preferences for AV1 as “enabled, use Dav1d” and preferences for VP9 as “enabled” but NOT “preferred”.
