我看到本论坛的另外一篇帖子了【71、72后，透明边侧栏收藏夹用不了了，大神们帮个忙，先谢谢了！ 】，说是添加【display: block; z-index: 1;】，我发现添加后，确实可以用了，但是有个问题，就是强制悬浮在那里， 不管怎么按ctrl+B，都无法关闭侧边栏。

lonely_8：加上
#sidebar-box:not(){
    display: block;
    z-index: 1;
}回到原帖

解决了，太强了！

tulip17：请问这个侧栏样式怎样使用？回到原帖

把样式放到chrome\userChrome.css里，按ctrl+B或H便可打开侧边栏，B是书签，H是历史。
