==有关字体的修改==
虽然可以借助「强制使用字体 - 核心」来写一个脚本让（几乎）所有网页都使用选定的字体列表显示，但那样的脚本也有不太合适使用的时候，因此将 Firefox 的默认字体列表修改一下以便在不想开启脚本的情况下也能使一些网站（比如维基百科，但维基百科并不属于「那样的脚本也有不太合适使用的时候」之情况）显示得好看一点还是有必要的。修改的方法为：直接将下方的代码复制并'''追加'''到 profile 目录下的 prefs.js 中即可。

p.s.: 目前这个区块是为 100% 缩放下的非高分辨率屏幕适配的。高分辨率屏幕以及 200% 等的缩放比例下使用这个字体列表可能并不好看。
