请帮我看下代码，怎么让标签页不挡住关闭按键

#appmenu-button {display: none !important; } 

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

/*工具栏向上移动多少px */
#main-window[chromemargin]:not([inFullscreen="true"]) #navigator-toolbox:not([customizing="true"]) {
  margin-top: -23px !important;/* 适当修改 */
}


@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: -25px !important;/* 適宜調整 */
}

#main-window:not([inFullscreen="true"]) #navigator-toolbox:not([customizing="true"]) > #PersonalToolbar {
  -moz-transition: max-height 0s ease-in-out .8s !important;/* 消えるときのアニメーション */
  -moz-box-ordinal-group: 1000 !important;
  padding: 0 3px !important;
  position: relative !important;
  z-index: 100 !important;
  overflow-y: hidden !important;
  max-height: 1px !important;
  min-height: 1px !important;
}

/*
#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 0s ease-in-out !important;/* 表示されるときのアニメーション */
  max-height: 30px !important;
}

}
