Linux版的默认图标太丑了，请问怎么替换？

主要是工具栏上的“书签”和“恢复关闭的标签页”两个图标

alanfly：书签图标爆丑，把下面代码放到stylish或者userchrome.css里换掉它。
恢复关闭的标签页默认没有的。

#navigator-toolbox[mode="icons"] #bookmarks-menu-button  {list-style-image: url("data:image/png;base64,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") !important;

回到原帖

感谢分享，恢复关闭标签页的图标我也找到了：

}

着实丑爆，默认主题的灰色系列还好看点（mac风格？

书签图标爆丑，把下面代码放到stylish或者userchrome.css里换掉它。

由你当前的gtk主题决定了.更换gtk主题就行了.这取决于你用哪个桌面环境

单纯改这些图标可不容易，这和系统主题有关，换个linux的主题，甚至换个linux的发行版，有能力的话也可以自己修改或写个主题安装。有些linux发行版下的缺省主题非常漂亮，如以前的linux mint 12下的mint-z。。。

另外就是装一个支持linux的firefox的主题，可选的不多，可以去mozilla addon网站安装。。。

對阿！為什麼图标都不一樣？誰選的阿？
