My most used bookmarklets increments playback speed for html5 videos, i have one that +0.5x and one that -0.5x javascript:(function() {var media = document.querySelectorAll('video,audio'); var rate = media[0].playbackRate+0.5; Array.prototype.forEach.call(media, function(player) {if (rate == null) {return;} else if (rate != 0) { player.playbackRate = rate; } else {player.playbackRate = 1;}}); })(); Also skip forward / back 30s javascript:(function() {var media = document.querySelectorAll('video,audio')[0];media.currentTime = media.currentTime+29;})(); Forgot: https://timelens.io/youtube/ https://timelens.io/youtube/ Great great for skipping past ads or blocks of content based on visual timeline.
