more information. The Advanced category The Advanced category (see Figure 16-8) contains options intended for experienced Internet users. Figure 16-8: The Advanced category contains some of the more complicated settings. These options are divided into the following three tabs. The General tab The General tab lets you configure Firefox's keyboard accessibility, some advanced browsing features, and how Web sites offered in multiple languages are displayed. Accessibility This area contains options that make Firefox more usable from the keyboard. Allow text to be selected with the keyboard: As you know, a flashing line in a text box indicates your typing position. Set this option to show a flashing line in Web sites you visit. Although you can't type into Web sites, you can select the text by using the keyboard, and the flashing line indicates where the selection will begin. To move the flashing line, click a spot on the page or use the keyboard arrows. Then, to select the text to the right of the flashing line, press Shift+>. Likewise, to select leftward, press Shift+>. The flashing line also indicates where on the page the Find Bar (which I discuss in Chapter 4) will begin searching. Begin finding when you begin typing: Set this preference to search for text on a page just by starting to type, without having to open the Find Bar first. See Chapter 21 for more information about this feature. Browsing This area lets you configure certain advanced features of the browsing experience, such as whether large images are automatically resized to fit in the Content area. Resize large images to fit in the browser window: By default, Firefox automatically shrinks large images so you can view them without scrolling. This feature kicks in only when you're viewing a large image on its own (for example, by right-clicking an image in a page and choosing View Image from the contextual menu). Large images within a Web page are not resized. When Firefox resizes an image, the mouse pointer becomes a magnifying glass as you move it over the image. You can restore a shrunken image to its original size by clicking it. Deselect this option to turn off this feature. Use autoscrolling: If your mouse has a middle button, you can use auto-scrolling to scroll a page quickly and automatically. See Chapter 21 for more information about this feature. Deselect this option to turn off autoscrolling. Use smooth scrolling: By default, Firefox scrolls a page in notches-that is, it bumps the page up or down a certain amount each time you scroll. Some people might find this behavior jerky when reading a document line by line. Turn on smooth scrolling to have Firefox slide pages up or down more smoothly each time you scroll. If you previously browsed in Internet Explorer, you might feel more comfortable with smooth scrolling because Internet Explorer uses it. Languages Firefox automatically detects the language of Web sites you visit so it can display them properly, but some sites are offered in multiple languages. Click the Edit Languages button to open the Languages window. Use the drop-down list and the Add button at the bottom of the window to add languages you understand to the language list, and then use the Move Up and Move Down buttons to organize the list according to your language preferences. When Firefox encounters one of these Web sites, it chooses the highest language on your list that the page supports. The Update tab
