url-addon-bar 书签图标撑大地址栏

在上一个版本39.0.2中，url-addon-bar是正常的，添加的扩展图标也没有出现撑大地址栏的情况。在今天更新到40.0.2的时候就会出现撑大地址栏的情况。各位有没有类似的情况应该如何解决？

是的，下载按钮也变大了，主要是官方内部的图标

大图标是为ｗｉｎ１０高分屏做到适配
等扩展更新吧

电脑分辨率提高会尝试使用2x分辨率，比如16*16图标，此时就会是32*32的，从而撑大。扩展需要更新，比如强制锁定使用16*16图标

/*导航栏高度*/
#nav-bar .toolbarbutton-1
{
margin-top: -8px!important;
margin-bottom: -7px!important
}
我是用这个解决的，但是前进后退按钮还是那么大

40+要定义图标大小。

谢谢提供代码！可是，这个拉伸的好丑，如何改？

该扩展的主页：https://addons.mozilla.org/zh-CN/firefox/addon/url-addon-bar/?src=userprofile已经有人提出这个问题了，不晓得作者最近有没有看见或者有时间修改，期待……

我给你的是后退按钮的，前进按钮是你自己的代码，so自己排查吧
