Some browser problems

Ugh, hopefully someone around here can help me out...

I have no idea what the fuck I did to mess up firefox...IE's having some difficulties too...


First off, smooth scrolling doesnt work. I think it has something to do with my video card properties, but basically, it's really choppy when I scroll. Smooth scrolling is disabled, but only because when it's enabled, it seems to make the scrolling go even choppier.
I think I downloaded something that fixed this (probably video card related), but I'm not sure what I uninstalled to make this shit happen again.

Secondly, when I ctrl+t, the cursor doesn't automatically go to the address bar. While this isn't a big deal, I know it used to go there automatically, and I'm not sure what's changed, or if that has anything to do with what's wrong.

Also, any streaming web pages won't work. Playlist.com, youtube, etc don't play. Nor does any sound come out when I'm playing a flsh game (iTunes is working fine, so it's not my sound card. Also, this is just a firefox problem. streaming sites work fine on IE)

Any ideas?

Hopefully I'm in the right place.
