你好，请问 油猴有自动隐藏书签的扩展么

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
    @-moz-document url(chrome://browser/content/browser.xul) {

    #main-window:not([inFullscreen="true"]) #navigator-toolbox:not([customizing="true"]) ~ #browser {
      margin-top: -28px;/* 適宜調整 */
    }

    #main-window:not([inFullscreen="true"]) #navigator-toolbox:not([customizing="true"]) > #PersonalToolbar {
      -moz-transition: max-height 0.2s ease-in-out .3s !important;/*这个是消失时的动画延长时间 */
      padding: 0 3px !important;
      position: relative !important;
      z-index: 100 !important;
      overflow-y: hidden !important;
      max-height: 0px !important;
      min-height: 0px !important;
      border-bottom: 1px solid ThreeDShadow !Important;
      opacity:0.85;

    }


    /*#main-window[stylish-url="about:blank"] #navigator-toolbox:not([customizing="true"]) > #PersonalToolbar,*/
    #main-window:not([inFullscreen="true"]) #navigator-toolbox:not([customizing="true"]):hover > #PersonalToolbar {
      -moz-transition: max-height 0.1s ease-in-out .6s !important;/* 这个是显示出来时的动画延长时间 */
      max-height: 30px !important;

    }
    #main-window[stylish-url="about:addons"] #navigator-toolbox:not([customizing="true"])  ~ #browser {
