I typically use Internet Explorer for web browsing. I know there are people who swear by Mozilla and Opera but for me, IE works pretty well.
Recently I've found myself trying and using Avant browser. Basically it uses IE components to create a better IE than IE. For instance, it has tabs, it has pop up stopping, it has all sorts of good, useful features. And by using it, you don't lose all yoru customizations, favorites, passwords, helpers, etc. from IE.
