    Last update 6 years ago but it still works and it's become more needed than ever now that YouTube is defaulting to a super low bitrate AV1 that looks god awful. thank you, wherever you are

    The downside is this also disables resolutions higher than 1080p. So we have to choose between uglier 140p - 1080p videos or no 1440p+. Ugh

    YouTube now defaults to AV1. The extension was last updated 6 years ago, so it still only blocks VP8/VP9.

    EDIT: After changing this setting to false in about:config it works: media.av1.enabled

    A must have for old laptops with no VP9 hardware decoding support. Just make sure that you can only watch videos up to 1080p.

    Doesn't seem to be working any more?... I just turned it on, restarted Firefox, and checked stats on a YT video, still says vp09

    It does block VP9 but I didn't notice a change in CPU usage...

    Doesn't really work. It's always avc codec, no matter what setting is set in h264ify, and when opening new youtube tabs 60fps isn't blocked.
    Please fix?
    UPDATE: Hmm, sometimes it works but not all of the time? Surely this needs some fixing. 4 out of 5 until then :)
