Firefox仅显示空白页面-甚至about:config只是白色 [英] Firefox shows only blank pages - even about:config is just white

问题描述

从一天到另一天，Firefox仅显示空白页面:

我尝试过

• 以-安全模式
启动Firefox
• 使用-ProfileManager 启动Firefox并创建新的配置文件
• 打开开发人员工具-但未显示
• 删除〜/.mozilla
• 使用 sudo apt purge firefox&&sudo apt安装firefox

什么都没用.Firefox甚至没有显示错误消息.铬仍能按预期工作.

解决方案

使用 strace 启动Firefox时，我偶然发现了一个名为 libAppProtection.so 的库.它位于/usr/local/lib/AppProtection/:

  $ ls/usr/local/lib/AppProtection/-lah总计188Kdrwxr-xr-x 2根root 4.0K Feb 23 17:35.drwxr-xr-x 6 root root 4.0K 1月1日08:24 ..lrwxrwxrwx 1根根56 Feb 23 17:35 libAppProtection.so->/usr/local/lib/AppProtection/libAppProtection.so.1.6.7.3-rwxr-xr-x 1根根175K 1月1日08:24 libAppProtection.so.1.6.7.3-rw-r--r-- 1根根44 Jan 1 08:24 .XInputEventIDs$ 

重命名文件夹后，我收到很多错误消息-在执行的每个命令上，甚至在shell中-但Firefox仍能按预期工作.

事实证明， libAppProtection.so 是

From one day to another Firefox shows only blank white pages:

I'v tried

• starting Firefox in --safe-mode
• starting Firefox with --ProfileManager and creating a new profile
• opening Developer Tools - but they did not show up
• removing ~/.mozilla
• reinstalled Firefox with sudo apt purge firefox && sudo apt install firefox

Nothing was working. Firefox even shows no error messages. Chromium still worked as expected.

解决方案

When starting Firefox with strace I noticed by accident a library called libAppProtection.so. It is located at /usr/local/lib/AppProtection/:

$ ls /usr/local/lib/AppProtection/ -lah
total 188K
drwxr-xr-x 2 root root 4.0K Feb 23 17:35 .
drwxr-xr-x 6 root root 4.0K Jan  1 08:24 ..
lrwxrwxrwx 1 root root   56 Feb 23 17:35 libAppProtection.so -> /usr/local/lib/AppProtection   /libAppProtection.so.1.6.7.3
-rwxr-xr-x 1 root root 175K Jan  1 08:24 libAppProtection.so.1.6.7.3
-rw-r--r-- 1 root root   44 Jan  1 08:24 .XInputEventIDs
$

After renaming the folder I got a lot of error messages - on every command I execute, even in the shell - but Firefox worked again as expected.

It turned out that libAppProtection.so was part of the Citrix Workspace App SDK 2101 which I installed some days ago. It needs a restart of Firefox to make problems. So I removed the current installation with

$ sudo apt purge icaclient
[...]
$

and downloaded the workspace app and installed it without the app protection:
