YouTube has this cool feature that isn’t all that common: It can instead of using a flash player, use html5 to play a video. The only thing you need is a modern browser that supports html5. Luckily most browsers these days support this. There are 2 methods of turning on html5 video for YouTube: Add “/html5” after a YouTube url (https://www.youtube.com/watch?v=noTbFgefN4o for a normal version and https://www.youtube.com/watch?v=noTbFgefN4o/html5 to use html5) Go to https://www.youtube.com/html5 and turn it on for all videos.
