The web browser everyone should be using these days is Mozilla Firefox. It has built in tabbed browsing, blocks pop ups, and lets you be reasonably sure you won’t get hit by the latest IE security holes. It’s also super fast and you can customize how it looks with easy to install themes.
There is also a less useful, but fun extension that enables “mouse gestures.” This lets you control the browser through pre-programmed mouse movements. For example, if you make an “h” it takes you back to your homepage.
