My personal favorite Opera - another great browser with tabs, pop-up blocking, and customization. Much more secure than IE, although you have to put up with a small banner add. Mozilla A browser suite. Includes tabs and pop-up blocking, as well as a mail client and IRC chat client. All your internet needs in one application.
