Detach YouTube videos from the page for autonomous playback and flexible size
If you use Chrome and you prefer sometimes to detach YouTube videos to watch them independently of their web page, on their own window which you can resize at will, from extremely small to extremely large, you only need this Chrome extension.
After you install it, in any YouTube page with a video you’d like to detach you will notice a red arrow button outside the top right corner of the video screen.
When you click this button your video stops playing and continues where you left it in a new window that opens containing nothing else but your video.
This new window can be resized at will and your video follows any dimension you may like being itself resized automatically and proportionally.
