The new start page fills the whole screen. You have to bump the cursor against the top margin to reveal the bar showing the tabs and the 'X' to close in the RH corner. At the bottom the start page covers the 'start' box and the information on the bottom row. Now I can't click directly on Bookmarks - I have to click the logo and then use the sidebar to access the bookmarks. I have also lost the ability to switch between the net and the document I am working on. This new configuration may suit some people, but the previous one was straightforward and better for me. How do I get it back, and prevent Firefox updating it again to this version?
