How to watch Youtube fullscreen on one monitor of a dual-monitor display, in Linux?

If I do it in Google Chrome, as soon as I do anything at the other monitor, Chrome jumps back to normal window.

Edit: added that OS is Linux.

Answer

Finally I stumbled upon a very easy solution:

• Go to a video on YouTube, in this example I am going to use http://www.youtube.com/watch?v=6v2L2UGZJAM


• 
  

  Modify the link slightly (this works with ANY video on YouTube)

  
  

  From: http://www.youtube.com/watch?v=6v2L2UGZJAM
  To: http://www.youtube.com/v/6v2L2UGZJAM

  
  


• 
  

  Enjoy your video!

  
  

You can also press F11 if you want to toggle between fullscreen mode (in your browser, not the video itself) which will increase the size of the image slightly.
