Use "https":// in the url field(Without the quotes), instead of just http. That should get you into facebook. You'll have to manually put the "s" infront of the http everytime you access a link in facebook though. I've yet to find a government PC that has blocked this method. Use at your own risk of course.
I'm assuming your using a Government pc, academy + CO springs = AF academy.
I was going to go to the academy when I enlisted. Then I deployed, like 6 months out of basic, and by the time I was eligible I was already established at my home station, deployed already, and couldn't take the paycut I would've gotten if I went to the academy.(Just bought a car)
Besides that, any senior that tried to give me *****, I would've slapped them silly.
