I am unable to type a url address in the firefox address bar. Same thing with the search box. When typing the letters, it will just disappear before I can get it typed in. I tried double clicking the menu box, help box and other icons, but it would only show for a brief moment and disappear.
Any suggestions? Just so you know, I am semi-computer illiterate. I am sure that myself or one of my kids have hit a button that has caused this problem. I just don't know where I need to start to fix it.
