Why would you want to disable them? Well, Java sometimes loads slowly, and JavaScript effects are sometimes so interactive they're just annoying. However, if you disable either technology, many Web sites might stop working properly. These options are intended only for advanced users who understand the consequences. Fortunately, you can prevent annoying JavaScript effects without turning off JavaScript entirely. See Chapter 21 for more information about this feature. Fonts and Colors Web site designers, like other artists, spend a great deal of time crafting their work. Nevertheless, you can override the fonts and colors used on Web sites to suit your tastes. See Chapter 19 for more information about these options. The Tabs category Use the settings in the Tabs category (see Figure 16-6) to configure the tabbed browsing experience. See Chapter 7 for more information about tabbed browsing, and the section on tweaking tabs in particular for help with each option. Figure 16-6: The Tabs category gives you control of your tabbed browsing experience. The Downloads category The Downloads category, shown in Figure 16-7, allows you to change the default destination of downloaded files and configure the behavior of the Firefox Download Manager. See Chapter 11 for more information. Figure 16-7: You can select a new location for downloaded files, configure the Download Manager, and teach Firefox your downloading habits. Download Folder By default, Firefox saves files you download to your computer's desktop so you can find and open them easily. However, you can modify this behavior: To be prompted for a destination each time you download, select the Ask Me Where to Save Every File option. To skip the prompt and save all files to the same location, select the Save All Files to This Folder option and click Browse to choose a folder. By default, Firefox downloads all files to your computer's desktop. Tip If you specify a default download location (or leave it as the desktop), you can override the save destination for a specific file by right-clicking the link to the file and choosing Save Link As. You can also press Alt (Windows) or Option (Mac) while clicking the download link. I discuss this feature at length in Chapter 11.   Download Manager By default, Firefox opens the Download Manager when you begin a download and leaves it open when the download finishes so you can open the new file. If the Download Manager is already open when a download begins, Firefox simply flashes the button for the window on your computer taskbar so you know. Deselect the Show Download Manager check box in this category if you don't want the Download Manager to open when you start a download. Alternatively, you can leave it on but select the Close the Download Manager check box to have the Download Manager close automatically when all downloads finish. Even if you select this option, Firefox (Windows) briefly shows an animated message in the bottom-right corner of the window when your downloads finish. You can click this message before it disappears to open the Download Manager and access the finished downloads. Download Actions Most people pick up certain downloading habits over the years. Every time I download a document, for example, I immediately open it in Microsoft Word. Firefox can save you time by automatically taking a certain action whenever a
