синтаксис файла профиля безопасности и информация о создании новых профилей приложений  (Security profile file syntax, and information about building new application profiles.)
  
Описание (Description)
Several command line options can be passed to the program using
       profile files. Firejail chooses the profile file as follows:
       1. If a profile file is provided by the user with --profile
       option, the profile file is loaded. If a profile name is given,
       it is searched for first in the ~/.config/firejail directory and
       if not found then in  /etc/firejail directory. Profile names do
       not include the .profile suffix.  Example:
              $ firejail --profile=/home/netblue/icecat.profile icecat
              Reading profile /home/netblue/icecat.profile
              [...]
              $ firejail --profile=icecat icecat-wrapper.sh
              Reading profile /etc/firejail/icecat.profile
              [...]
       2. If a profile file with the same name as the application is
       present in ~/.config/firejail directory or in /etc/firejail, the
       profile is loaded. ~/.config/firejail takes precedence over
       /etc/firejail. Example:
              $ firejail icecat
              Command name #icecat#
              Found icecat profile in /home/netblue/.config/firejail
              directory
              Reading profile
              /home/netblue/.config/firejail/icecat.profile
              [...]
       3. Use a default.profile file if the sandbox is started by a
       regular user, or a server.profile file if the sandbox is started
       by root. Firejail looks for these files in ~/.config/firejail
       directory, followed by /etc/firejail directory.  To disable
       default profile loading, use --noprofile command option. Example:
              $ firejail
              Reading profile /etc/firejail/default.profile
              Parent pid 8553, child pid 8554
              Child process initialized
              [...]
              $ firejail --noprofile
              Parent pid 8553, child pid 8554
              Child process initialized
              [...]
