Although, we are not necessarily endorsing one over the other, they serve the same function, some are easier to use. It is a matter of what you get comfortable with. Netscape currently has the corner on the market. Most users access this Browser. Email is also accessible through a Browser.
All Browsers have tool bars which run across the top of the screen.
The tool bars have different buttons for different functions. For example, a button which takes you to the page you previously viewed, or a button to take you to the page following the current one you are viewing. Most Browsers have a tutorial or help section which describes respective features and how to use the browser. Depending on the Browser you are using, you should now be able to see the tool bar and features running across the top of your screen.
