Tabbed browsing is a relatively new feature found in some Web browsers. Tabbed browsing is a function of some Web browsers that allow uses to surf and view multiple pages by loading the Web sites into "tabbed" sections of one page, rather than multiple pages. This allows the user to view a selection of favorite sites in one window, view multiple search results at the same time, and would allow you to set several pages as your home page, rather than just one.
Currently, you will find tabbed browsing available in the following Web browsers; Mozilla/Firefox, Opera, Apple's Safari, AOL's Netscape and the Linux-based Konqueror. Some third-party browsers based on the Internet Explorer engine that also offer tabs include MyIE2 and Avant browser.
The first browser to offer tabbed browsing was InternetWorks in 1994, but the feature did not become popular until Mozilla incorporated the function into their browser in 2003.
