I'm an Amazon bookseller and when I click on the New and Used book designations on an Amazon book web page I get a weird page that is incomplete and unusable. I've updated my Firefox, tried different books, and tried using Google where the page displays correctly. I've called Amazon and they said it's a Firefox problem. The page does not display all the books for sale and there is no scroll bar. I've attached a screenshot. I'm using Windows 10.
