Vimeo/YT exit fullscreen when focus not on player

[himmi]

I have more than one monitor and when I put YouTube/Vimeo (haven't tried anything else) videos on fullscreen and put the mouse focus on an application on another monitor the video exits fullscreen.
This is very annoying because I'm watching Blender tutorials on one screen and have Blender open on another screen.
Any fix for this?

I have Linux Mint 14 MATE 64-bit.

Thanks.

Same situation here, watching my music playlist while working on my cocnky scrips or whatever else I'm messing with on my second monitor. Definitely annoying lol.
