How Stop Pop-Up Window: Allow Fullscreen With Keyboard Controls?

This is really starting to **** me off. I am tired of seeing this Window Pop Up all the time. When i play Facebook Games and at other times. How do i Disable this and don't you ******* dare tell me i can't. Its my ******* computer and i have every right to change whatever ******* settings i want. I have searched all over the internet to remove this and i am tired of you all screwing us all over the place.

     You tell people this crap (Due to security concerns, this is not currently possible.  While not exactly the same, this feature request might be something you'd like to vote for)

     I vote for it now. I pulled that from a post over 3yrs and over that ******* time you still haven't put it in.

SO WHAT I AM SAYING AND THIS REALLY AIN'T A QUESTION YOU NEED TO SET THIS TO WHERE WE DON'T SEE THIS ANYMORE. GET OFF YOU BUTTS AND DO SOMETHING INSTEAD SITTING IN YOUR OFFICE DRINKING COFFEE
