有小巧简洁的鼠标移到侧边自动弹出侧边栏的扩展吗

虽然这个能用，但不会调整颜色，也不知道怎么放到右边。也没人帮忙改。就想换扩展了
//自动隐藏侧边栏
@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
#sidebar-splitter{display:none !Important;}
#sidebar-box{position:fixed !important; width:200.01px !important; top:72px; bottom:0px; left: -207px !important;
-moz-appearance: none !important; -moz-transition: left .001s .2s ease-in; padding-right:1px !Important;}
#sidebar-box:hover { left:0px !important; -moz-transition: left .001s .3s ease-out;}
#sidebar-header{display: none !important;}
#sidebar{height:100%; width:100%!important;border-right:2px inset -moz-use-text-color !important;}

只能等着别人来解决了。高端的火狐爱好者好像不喜欢css
