How do I get to the "Firefox screen" and the "Firefox button"?

I need to reset Firefox (ver 18 running on Vista Home) to fix problem with downloads. But I can't get to the troubleshooting screen. There is no "Firefox screen" and there is no "Firefox button" on our computer. If I don't have a Firefox screen or a Firefox button, what other way can I reset the browser? Thnx!
