Why can't i see ppl on omegle?

I can see myself but the strangers can't see me and i can't see them. My friend can see almost every stranger that she talks too on her laptop and it annoys me so much! Chatroulette works fine for me but i like omegle more. I use google chrome ( i have also tried safari and firefox) on macbook air and she uses internet explorer on her lenovo windows 8 laptop
