the only error is me, but!

hello,
Not only do I not have the knowledge to operate this very nice computer, It took me 15 min. to figure out where to type a question.
Anyway I do have a problem that I created here, and would appreciate any help. I have been looking thru some threads and you seem like a really nice group to deal with so here goes.
I got frustrated playing a game , and kinda danced my fingers on the keyboard randomly.
now I get an error message saying error 404, url not found. It's always there when I open firefox.
not really a big deal, it goes away if I close the tab. BUT, it really makes me feel stupid everytime I see it.
thanks
