I have Windows XP Pro. I upgraded to FF 4 yesterday & most everything is there (but in different places). However, I use FF as my browser homepage & can't get rid of a "commercial" menu that appears below the Google menu window. The latest commercial is (pasted) "Want to see what the Web is really capable of? Explore the Web o' Wonder demo gallery and prepare to be amazed!" How do I get this off my home page?
