Red Hat Enterprise Linux comes with several Web browsers, graphical applications that use your Internet connection to access the World Wide Web: news, research, shopping, banking, and more. This chapter briefly explains how to surf the Web using Firefox. For information about using the Konqueror Web browser, refer to Section A.6 Browsing the Web with Konqueror.

6.1.1. Using Firefox

Firefox functions like any Web browser you may have used before. it has the standard navigational toolbars, buttons, and menus.

The Navigation toolbar contains navigation icons, the address bar, and a search field.

Enter a Uniform Resource Locator (URL) — the name or address of a web site — into the address field. Firefox moves immediately to the web site.

The Search field uses the most popular search engines to look for sites related to the keywords you enter. Select the search engine Firefox should use by clicking on the icon at the left of the field. Enter the keywords and press [Enter] to perform the search.

Firefox has a sidebar to aid in navigation. Select View => Sidebar form the main Firefox toolbar, then choose the detail to display. You can choose from your bookmarks or the history of websites you have visited.

Finally, the Personal Toolbar can be customized with the web sites that you visit most often. Web sites added to this toolbar become buttons — one click, and Firefox moves to that web site. To add a site to the Personal Toolbar, drag the site's icon from the address field to the Toolbar.

6.1.2. Tabbed Browsing

Firefox offers tabbed browsing. Tabbed browsing allows a user to flip quickly between web pages without opening another instance of Firefox. Right-click a link and choose Open Link in New Tab to use this feature. Open a new tab by selecting File => New Tab or by pressing [Ctrl] -[T] .

6.1.4. Extensions and Themes

There are many extensions and themes available for Firefox. Extensions are small applets (smaller than plug-ins) that provide additional functionality to Firefox. For example, there is an extension called ForecastFox that adds a small toolbar at the bottom of Firefox that includes the local weather forecast. This and other extensions are available by going to the Tools menu and selecting Extensions. To add new extensions to your Firefox browser, click the Get More Extensions link in the bottom right of the window.

Themes allow you to change the way your browser looks. They change the color of the browser window and the icons on your toolbars. To download and install new themes, open the Themes tool by selecting Tools => Themes from the main toolbar. Click the Get More Themes link in the bottom right of the window.
