YouTube Auto HD + FPS - Chrome Web Store
chrome.google.com › webstore › detailThis means, for example - if your computer can handle 1080p videos at 30 FPS, but not at 60 FPS - you can automatically set 60 FPS videos to play at 720p! And the best part - it works for embedded YouTube videos as well! (I.e. YouTube videos that aren't in YouTube.com) It can even automatically resize videos according to your preference!
