even create new toolbars. See Chapter 18 for more information about toolbar customization. Status Bar Shows or hides the Status Bar at the bottom of the window. The Status Bar displays information about the current page. See Chapter 2 for more information about the Status Bar. Sidebar The Sidebar submenu allows you to show or hide sidebars, which are vertical bars that open on the left side of the Firefox window. Firefox includes two sidebars by default; the Bookmarks Sidebar, which I discuss in Chapter 5, and the History Sidebar, which I discuss in Chapter 6. You can also set book-marked Web pages to load in a sidebar, as I discuss in Chapter 5. Finally, certain extensions install their own sidebars; see Chapter 20 for more on extensions. Bookmarks Shows or hides the Bookmarks Sidebar, which contains your bookmarks list. Shortcut Ctrl+B or Ctrl+I ( +B on a Mac) See Chapter 5 for more information about the Bookmarks Sidebar. History Shows or hides the History Sidebar, which contains a list of sites you've visited recently. This command is the same as choosing Go History. Shortcut Ctrl+H ( +Shift+H on a Mac) See Chapter 6 for more information about the History Sidebar. The list of installed sidebars If any extensions have installed new sidebars, a menu item for each appears here. For example, the Scrapbook extension I discuss in Chapter 22 installs its own sidebar. Click the menu item to show or hide the sidebar. See Chapter 20 for more information about extensions. Stop Forces the current Web site to stop loading even though it hasn't finished. Only the part of the page that has finished loading will be available. This is the same as clicking the Stop button on the Navigation Toolbar. This command is unavailable if the current Web site is already loaded. Shortcut Escape Reload Fetches the newest version of the current Web site. For example, you might want to leave the CNN Web site open and reload it occasionally to see the latest headlines. This is the same as clicking the Reload button on the Navigation Toolbar. Shortcut F5 or Ctrl+R ( +R on a Mac) Text Size The Text Size menu allows you to enlarge or shrink the text of Web pages you view in the current tab or window. See Chapter 19 for more information about changing text size. Increase Enlarges the text on the current page and all future pages visited in the current tab or window. Use this command repeatedly to enlarge the text further. Shortcut Ctrl++ ( ++ on a Mac); in other words, press Ctrl (or on a Mac) and the plus sign Decrease Shrinks the text on the current page and all future pages you visit in the current tab or window. Use this command repeatedly to shrink the text further. Shortcut Ctrl+- ( +- on a Mac); in other words, press Ctrl (or on a Mac) and the minus sign Normal Returns the text size of pages you view in the current tab or window to normal, regardless of how much you increased or decreased it previously. Shortcut Ctrl+0 ( +0 on a Mac)
