I found exactly what you are talking about. But i can not edit my default browser. All i can do is highlite it or copy it. I have no option of deleting the text and adding my own..
Sorry I misunderstodd. When you said "set the home page" I thought you meant "set the home page to a certain url". Like Xliderider said above, you cannot "change" the default browser.
