Can anyone help me with my mac/myspace problem?

I use myspace to listen to music. For some reason when I am at college myspace freezes my browser but when I go other places it does not. I am running firefox on a mac through a wireless network. My friends on the same network running windows have no problem. can anyone help me?

edit: for the record I have tried other browsers and while they don’ completely freeze i still cant access myspace music or video
