You lot wouldnt be allowed an internet connection... Geesh, if you cant install a different browser what chance if you having a secure internet connected computer...
(yes, I'm taking the pee but seriously, if you cant install an alternative, how do you know there isn't something better out there.... ) it's a bit like still driving around in a 1970 s car because you didn't know that they had got better and then crashing into the shiny new car in front because he has much better tyres and brakes....
