Opera USB 9.50
Opera USB is the portable version of the third most popular browser and excellent Internet Explorer alternative, Opera. The idea is quite simple with the browser having been stripped down so as to fit on your USB key and used on whatever computer you happen to be working on.
It supports all the functions that you are used to in the full version so you won't miss the email client, IRC, the download manager, and of course your favorites.
Opera USB doesn't install any extra components on the PC you use, and doesn't alter other browsers in any way.
