I love Firefox.....That is all that I will use....Since I got my new computer, I have used it, and one day someone was fooling around on my computer and deleted it, so I had to use explorer to download it again, and the second I got explorer up, there were about 25 windows that opened up, and each one had like 5 words on it, and the more I tried to close them the more of them popped up. When I finally did get them to close, I ran a virus scan, and there were 15 viruses on there from explorer, so I NEVER EVER use explorer....mozilla firefox also has some cool stuff on it, like where you can open up to like 20 different tabs in the same window, and that way you can just go back and forth between tabs instead of having to try to find where your window went in the taskbar...I love that part. All in all, I would definately have to say that Firefox is better in my opinion. Hope this helps....I know it's kinda late!!

Oh yeah, it is really easy to download too. Go to your search box and just type in "free mozilla firefox download" and it will take you right to the page, and it just takes a minute....and then you just don't use explorer anymore.......
