From one day to another Firefox shows only blank white pages:
I'v tried
--safe-mode
--ProfileManager and creating a new profile~/.mozilla
sudo apt purge firefox && sudo apt install firefox
Nothing was working. Firefox even shows no error messages. Chromium still worked as expected.

Clear the cookies and cache If a website has updated their code, Firefox may still be using some of the old code along with some of the new, which can make a web page display incorrectly. To fix this, you need to clear the cookies and cache: Click the menu button. to open the menu panel.
"Show a Blank Page" To set this as your default, click on the "Firefox" button and choose "Options." When the Options dialog box opens, click on the "General" tab and set the "When Firefox Starts" drop-down menu to "Show a Blank Page."
When a Web page is blank, there are a few likely reasons. The reasons fall into three categories: 1, a server-related problem; 2, a network problem; and 3, a client browser or computer problem.
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:
