This morning I turned on PC where FF is set as home page. There was a large pop up in middle of screen with some sort of new color change options for home page. I liked what I saw and was testing some designs, but I cannot get it back. I had hit the "use previous selection", I believe what it said, and it went back to my original screen. I thought it would go to the one I had chosen, a deep green background. At any rate, how can I get this option back to try again...? Thanks LT in Winnipeg
