To override the fonts defined by such pages, uncheck the Allow pages to choose their own fonts, instead of my selections above &pref.singular;.

You can set your default colors by going to &pref.menuPath;, selecting the Content panel, and clicking the Colors button in the Fonts & Colors section. You can set default text and background colors, as well as default colors for visited and unvisited hyperlinks. You can also specify whether hyperlinks should be underlined.

Turning Off Java Applets

停用 Java Applets

Some web pages provide a rich interactive experience with Java™ applets. However, some users that rely on keyboard navigation may experience problems with some Java applets that automatically set focus and do not provide a way to break out of the applet and navigate to the rest of the web page. If this is a problem for you, you can disable Java by going to &pref.menuPath;, selecting the Content and unchecking the Enable Java &pref.singular;.

有些網頁會用到 Java™ applets 提供豐富的互動體驗。但有些只能靠鍵盤瀏覽的 使用者卻會因為 Java applets 自動切換焦點卻沒有提供「跳離」該 Applet 的方式 而在瀏覽網路時遇到困難。如果這會對你造成困擾，你可以從 &pref.menuPath;， 選擇內容面板，不要勾選 可使用 Java &pref.singular; 取消對 Java 的支援。

Restricting JavaScript Behavior

You can turn off JavaScript entirely by going to &pref.menuPath;, selecting the Content panel, and unchecking Enable JavaScript. Some web pages rely on JavaScript and may not work properly if JavaScript is disabled.

你可以完全關閉 JavaScript 的支援。從 &pref.menuPath; 中， 選擇 內容面板，不要勾選可用 JavaScript 的選項即可。 但有些網頁會因為 JavaScript 被關閉而無法正確執行。

If you do not wish to disable JavaScript entirely, there are also a number of advanced JavaScript settings to restrict the behavior of scripts. Immediately after the Enable JavaScript checkbox, click the Advanced button to open the Advanced JavaScript Settings window. You can control whether scripts are allowed to move or resize existing windows, raise or lower windows, disable or replace context menus, hide the status bar, or change status bar text.

若你不希望完全關閉 JavaScript ，我們提供了一些有關 JavaScript 的設定限制其行為。 請按下可用 JavaScript 後的進階按鈕，打開 進階 JavaScript 設定視窗。你可以設定是否允許 scripts 移動或改變視窗的位置或大小、停用或取代右鍵選單、隱藏或改變狀態列的文字等。
