"去掉启动显示书签栏"和"主页和新标签显示书签栏”因为想用stylish来取代
https://github.com/feiruo/userChromeJS/blob/master/AwesomeBookmarkbar.uc.js
这是stylish
@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
#main-window[stylish-url="about:home"] #PersonalToolbar,
#main-window[stylish-url="about:blank"] #PersonalToolbar,
#main-window[stylish-url="about:newtab"] #PersonalToolbar {
visibility: visible;
}

那你用这个脚本还有什么意义

你说的那些用样式就能解决，脚本禁用了吧
/*自动隐藏*/
#PersonalToolbar {
width: 100% !important;
position: fixed !important;
background:#fff!important;
margin-top:-30px !important;
transition: .6s ease-out 3s!important;
z-index: -1;
opacity: 0 !important;
}

#nav-bar:hover~#
PersonalToolbar,
#TabsToolbar:hover~#
PersonalToolbar,#PersonalToolbar:hover {
margin-top:0 !important;
transition: .1s ease-in 1s!important;
z-index: 1;
