firefox is usually the one that shows the page exactly the way the code is written.
the other two will try and guess what you intended it to do and show that way. often it is right but in my opinion, you should correct the code when it looks wrong in firefox.
In this case, you have put the code for the slider in without removing the other stuff that takes up the same space.
the h1 tags are empty but still there, the <P> tags are still there. they both take up space.
you also did not change the css for the site description div so it is taking up 65% of the headerbar and making it float left.
I'm baaaaaccckkkk. still doing work on donation basis. PM your needs.
