Tired of YouTube not automatically setting videos to the appropriate quality?
This extension will not only let you specify the quality of the videos, but will also consider FPS!
This 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!
