I downloaded but how do I install this? I have Internet Explorer and I want to try Fire Fox as my search engine.

I am not computer savy. sorry. I have downloaded from your Firefox.com and still show Internet Explorer at the top of my screen. Before I take that icon off my desktop I need to know how to get the Firefox on there and be able to use it. I have google as my home page. Can that stay for my home page? I cannot use this until I get help. might have to have someone of my friends come and help me get this functional. I really was wanting to change from IE cause it is so slow.
