Weird formatting in Firefox?

Hey guys,

Just wanted to point out I am having some site formatting issues that just started in Firefox. This is FF16.0.2 running on OS X 10.7.3. Safari is not displaying this problem as can be seen by the screen cap. I flushed my cache and cookies and relaunched FF to no avail.

First one is proper in Safari and second one is how it is appearing in FF. This just started happening this afternoon at some point.

I'm getting the same thing.

That's what I was getting last night too, but was fine at work today.
