One can easily view YouTube videos in fullscreen with just a click of the button. But the full screen option offered by Youtube occupies the entire desktop screen which you might not want every time. Here is an easy way to ‘Set YouTube videos to Play in full screen mode by default’ and they will expand to entire window of your browser only.
To Set YouTube video to play in full screen by default, just replace watch?v= with v/ in the video link. An example of same is given below:
Original URL – http://www.youtube.com/watch?v=9Kyb7U_djUk
Modified URL – http://www.youtube.com/v/9Kyb7U_djUk
Then use the modified video URL or share it to view Youtube videos automatically within entire area of your browser window. 😉
