Open source web browser
Mozilla Firefox is an unaffiliated web browser that offers tabbed browsing combined with numerous handy features like popup blocking, Live Bookmarks (RSS integration), password manager and much more. The functionality can be expanded with dozens of freely available plugins (Extensions). Firefox can import some other settings as well as all of your Web Browser Favorites, so switching is made easy. The default attributes of Firefox are good for basic web-surfing. An abundant group of freely available extensions (addons) enable you to readily add the features you want and customize the browser to meet your needs.
