Apps unable to load config/profile of $USER

[onny]

Hey,
I'm packaging orjail for NixOS NixOS/nixpkgs#138293 and it's already working :)

One issue is that if I run, for example firefox with orjail, firefox will use a new and empty profile instead of my own located in /home/onny/.mozilla/firefox:

sudo orjail -v -f firefox
orjail (id: 0)
orjail network namespace already exists!
Switching to pid 47966, the first child process inside the sandbox
Child process initialized in 7.46 ms

If I run firefox with firejail directly, I have the firejail sandbox but also my Firefox profile loaded:

firejail firefox

Maybe this behavior is related to NixOS or is this intended?
