A web browser is something like internet explorer, firefox, Google chrome, etc. Most of the top features people want are speed and protection. Now, I recamnd getting google chrome because its REALLY fast. My internet explorer took 10 seconds to load a page and google chrome took barley a second. But if you want a browser thats good for customizing, get firefox. Its fast, but not a fast as google chrome. Also, google chrome has SOME customization features, like changing the adress bar texture/color.
