推荐答案

FIXED:这时候的解决办法是降级火狐！运行此命令以获取可用 Firefox 版本的列表.

FIXED: Solution at this time is to downgrade Firefox! run this command to get a list of available Firefox versions.

apt-cache show firefox | grep Version

我的结果:

Version: 47.0+build3-0ubuntu0.16.04.1
Version: 45.0.2+build1-0ubuntu1

安装:

sudo apt-get install firefox=45.0.2+build1-0ubuntu1

要保留此版本并禁止更新:

To keep this version and disallow updates:

sudo apt-mark hold firefox

如果您想取消保留 Firefox 版本并允许更新:

sudo apt-mark unhold firefox
sudo apt-get upgrade
