改變高亮關鍵字時的顏色

Firefox 默認使用 Highlight all 時，高亮關鍵字的顏色是粉紅色
能不能指定成別的？例如黃色。不考慮裝其它套件，希望能用 Stylish 修改。

about:config里可以改；

ui.textSelectBackground (String): Determines the background color to use for text selections as a hex code or named color. If this preference is not set, the OS's value is used.
ui.textSelectBackgroundAttention (String): Determines the background color used for Find As You Type as a hex code or named color. If this preference is not set, the inverse of ui.textSelectBackground is used.
ui.textSelectForeground (String): Determines the text color to use for text selections as a hex code or named color. If this preference is not set, the OS's value is used.

用 textSelectForeground 為關鍵字找不到相關參數呢。
Firefox 版本是 9.0。

自己新建对应项，默认没有。
