Maybe someone else can experiment on those platforms. This may be a recent Firefox development, and it might not be available in ‘Windows’ or ‘OSX’. This will bring up a little search box that will search the entire contents of the page, including all of the comments you just finished loading. If you’re using a Mac, you’ll need to hit Command and F instead. 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. Once you get to the bottom, use your keyboard and hit Ctrl and F at the same time. Features: Quick search by timestamp, author, content. Search comments, replies, chat replay, video transcript for the current video on YouTube by contents, authors, time.

(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. The YCS (YouTube Comment Search) is a chrome extension.

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”.
