【扩展推荐】The Puzzle Piece 找回firefox29+附加组件栏

配合以下样式服用更佳==
@namespace十十 url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
/*====缩小图标===*/
#urlbar-icons image{padding: 0 !important; margin: 0 2px !important;}/*调整图标间距*/
/*====全局去小三角===*/
dropmarker {display: none !important;}#greasemonkey-tbb dropmarker{display:inline!important;opacity:0;margin-left:-23px!important;} /*====显示油猴子的小三角并偏移===*/
如果你觉得自带的addon in url bar 功能不够方便，还想要把那个绿色拼图图标也隐藏掉，可以先取消自带的隐藏，然后用一下样式
/*===========自动隐藏 Addonbar==只针对此扩展有效=========*/
#urlbar-icons #thePuzzlePiece-urlbar-addonbar-container,#thePuzzlePiece-urlbar-PP{visibility: collapse;opacity: 0 !important;-moz-transition: opacity 0.3s ease-out, visibility 0.3s ease-out !important;}
#urlbar:hover > #urlbar-icons #thePuzzlePiece-urlbar-addonbar-container,#urlbar:hover > #urlbar-icons #thePuzzlePiece-urlbar-PP{visibility: visible !important;opacity: 1 !important;-moz-transition: opacity 0.2s ease-in, visibility 0.2s ease-in !important;}
#urlbar[focused="true"] #thePuzzlePiece-urlbar-addonbar-container {display: none !important;}

效果图==

好东东，顶啦~~

这个不错

隐藏那个绿色拼图 图标 这个css 不起作用啊 咱设置才行啊
#urlbar-icons #thePuzzlePiece-urlbar-addonbar-container,#thePuzzlePiece-urlbar-PP{visibility: collapse;opacity: 0 !important;-moz-transition: opacity 0.3s ease-out, visibility 0.3s ease-out !important;}
#urlbar:hover > #urlbar-icons #thePuzzlePiece-urlbar-addonbar-container,#urlbar:hover > #urlbar-icons #thePuzzlePiece-urlbar-PP{visibility: visible !important;opacity: 1 !important;-moz-transition: opacity 0.2s ease-in, visibility 0.2s ease-in !important;}
#urlbar[focused="true"] #thePuzzlePiece-urlbar-addonbar-container {display: none !important;}
