My Facebook is Messed Up?

So this starting happening near the beginning of this week...I went to Facebook and the layout was all messed up.
What's up with Facebook? My home page is a freaking mess with posts all on top of each other and general mayhem on the whole site. I'm Running Vista Service pk1.
Now I can't see who's online because like everything in the toolbar at the bottom doesn't work. On the left, it has all my apps, in the middle, its my news feed, and on the right, it is pretty normal. Pretty messed up. There are lines dividing all those sections. At the top, it has the facebook sign and then it has a people kind of picture and then my messages and then my notifications.

What can I do to fix my facebook profile?

I'm having the exact problem. My friend suggested it might be a cookie issue or problem with my anti-virus. But facebook is the only site I have this problem on, also I deleted my cookies and have 2011 Norton Internet, so what the heck is the problem and why do none of my other friends have this issue?
