One of my favorite things about Firefox is its find function.  All you have to do is press Ctrl+F and start typing, and Firefox finds things as you type.  Or you can just start typing (without first pressing Ctrl+F), but that doesn't always work.  It works a lot better than the Internet Explorer find function, which requires you to type in what you're trying to find, press enter, and then wait for it to tell you it couldn't find anything.  Firefox is a little more intuitive in that way.
