Cursor doesn't change
When you are over a hotspot on the page such as a thumbnail, the cursor remains as an arrow in my version of Firefox. It's only through intuition that I still clicked on one and found myself where I thought I was going. When using that method to navigate from the opening page, my back button wasn't highlighted and that was confusing. I believed I should be able to return to that page.
That's as far as I got.
