Top sites on Safari 4 beta and watching movies on netflix crash my browser

[oneshot]

Whenever I try to view Top Sites on safai 4 public beta my browser crashes. Now I'm completely all right with that and its not a big deal but what is very annoying is that my browsers (safari and firefox) crash whenever trying to view netflix "view it now" videos.

Does this have to do with my video card or what? Everything works fine with my video card accept I keep getting random web browser crashes while trying to do cretin things on it but the two that I remember happening because they happen every time are Top Sites and Netflix.
