fullscreen youtube dual monitors

[netopalis45]

Using a dual monitor setup with Ubutnu 12.04 and an nVidia video card. I would like to be able to watch youtube fullscreen on one monitor while doing something else on the other. The problem is that as soon as I click on something on the other monitor youtube exits fullscreen. Is there any way of stopping that from happening?

This is how I did it:
1.) Open your video you want to play on your second monitor.
2.) Right-click the video and press "Pop out"
3.) Move the popped out video to your second monitor.
4.) Press F11 (for fullscreen)
5.) Done!

i have youtube in fullscreen on my second monitor, but whenever I click somewhere, the fullscreen youtube immediately shrinks back to normal size in the web browser.
