There is another way too. Go to www.portableapps.com You can download firefox and many other utilities that you run on a thumb drive. It is a good idea to have all this stuff with you anyway. The thumbdrive acts like a portable hard drive and you can load up let's say like an 8 gig thumbdrive with all the goodies you might need. You can run Firefox right from that drive as long as the PC your have at your access has a USB port and internet access. I have an 8 gig that I carry around with me all the time, but I am a geek that way I guess.
