I was mucking around with themes today & now, when I open a new tab, it doesn't show my most frequently visited sites, it just shows a blank page. I have had this problem before & somewhere managed to fix it, but now, I've gone through everything & I just can't figure out how to get it back the way it was. Can anyone help me? When you click on a new tab, you have pictures of the page of the most visited sites & more listed down the right hand side. It is NOT top sites..
