[Camino] question about camino

I have used Camino for awhile but a child was playing on the computer and
now when I open Camino it is  Camino.Start and it doesn't give me a place to
put a web address.  also there are no "back" arrows to click on to return to
where I was on the internet.  Can you tell me what I can do to get it back
where I can enter an web address when I open Camino?

Thank you for your help.
