I'm looking for a distro to run off of a usb so I can use linux when I am out of town with friends and using their computers. I just want a fast loading distro for firefox basically, preferably one that gets updated frequently. It doesn't have to be very full featured as long as I can run firefox and save my changes and settings. I was just wanting to get some opinions as I know some of you guys test tons of distros... I'm looking at you exploder.
