When I open Firefox there are always 2 tabs visible. The first is my homepage and the second is my options. How can I stop options from appearing as a second tab. I can reach options through the menus if I need it. It is annoying to have to close it each time I open Firefox.

Thanks. It was the latest version but in my homepage area it said: "http://my.xfinity.com/?cid=customer|about:preferences#general" I deleted the "|about:preferences#general" and all was fine.
