Here’s a guide to the most popular Web browsers:

Explorer (www.microsoft.com/ie): From Microsoft, this has the largest market share, at about 60%, primarily because it is built in with the dominant Windows operating system. New features of the latest version 7.0 include improved security and tabbed browsing.
Firefox (www.getfirefox.com): A very popular open-source Web browser for Windows, Linux and Mac, it is easy to customize with special extension add-on programs and is known for its speed and effectiveness in blocking popup ads. It’s generally seen as the most full-featured of the Web browsers.

Opera
(www.operanetscape.com): Some people swear this is the fastest, most responsive Web browser. Among its features, it offers mouse gesture navigation to do frequently performed browse operations like going backward or forward or returning to the home page by making small, quick mouse movements.

Netscape (http://browser.netscape.com/ns8/): Yes, there still is a Netscape. Displaced by Microsoft’s IE in 2002 as the most popular browser, it’s been redesigned as leaner and is among the most secure of the browsers, with a heavy emphasis on protecting against spyware and adware.

Safari (www.apple.com/safari/): This works only with Apple computers. It’s among the fastest of the browsers and among the most secure from hackers. It offers very advanced RSS features, or the ability to collect and access relevant news feeds from other Web sites or blogs about specific information you’re interested in.
