Firefox

Opera

If you use still use Internet Explorer, stop. Now. I mean it. Firefox or Opera are better in practically every way.

They are more secure (no more spyware from just browsing to a site). They block pop-up advertisements. They have "tabbed browsing", which means you can have more than one page open at a time.

Firefox has hundreds of extensions available that will let you do everything from downloading an entire site to making advertisements completely disappear. You can increase or decrease a page's font size with just a keystroke or mouseclick.

Opera has a built-in IRC client, built-in note-taker, built-in image zoom, mouse gestures, customizable style sheets. Loads and runs faster than Internet Explorer.

They are both better than Internet Explorer.
