Some web sites may display text in fonts that are difficult to read, and other sites may rely on the browser's default fonts. You can set your default fonts by going to &pref.menuPath;, selecting the Content panel, and selecting a default font and size in the Fonts & Colors section.

有些網站使用難以閱讀的字型顯示文字,有些則用瀏覽器的預設字型顯示。您可以從 &pref.menuPath;, 選擇內容面板後,到字型與色彩設定你的預設字型與大小。

You can specify default fonts for different styles, including serif, sans-serif, and monospace by clicking the Advanced button.

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

你可以按下進階鈕為預設字型設定不同樣式。由於許多網頁會自行指定字型, 你的設定有可能會被忽略。要強制使用你自己的字型,請不要勾選優先使用網頁指定的字型 &pref.singular;。

Note that some web pages may display incorrectly depending on your choice of a default font.

註:有些網頁可能無法正確的顯示你設定的字型。

有些網站的字型設定過小以至無法舒適的閱讀。你可以設定最小字型大小讓這些頁面更容易閱讀。 &brandShortName; 會以你設定的最小大小為準顯示。

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.

有些網站使用難以閱讀的文字或背景色彩顯示,有些則使用瀏覽器的預設色彩。 你可以從 &pref.menuPath; ,選擇 內容 面板後,並按下 字型與色彩中的色彩按鈕設定預設色彩。 你可以設定預設的文字與背景色彩、已拜訪或未拜訪的鏈結色彩,甚至選擇鏈結下方是否要加底線。

However, many web pages set their own colors, so your choices will have no effect. To override the colors defined by web pages, uncheck the Allow pages to choose their own colors, instead of my selections above &pref.singular;.

由於許多網頁會自行指定色彩,你的設定有可能會被忽略。要強制使用你自己的色彩設定, 請不要勾選優先使用網頁指定的字型 &pref.singular;。

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

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。
