Under debian based distros, overriding an overwrite of ANY installed
file is easily done.
There's a really cool tool called dpkg-divert that the system uses to
take whatever files would normally be installed and steer them into a
different place so that you can put your own version of the file in the
same place without fear of it going away on the next update.
Just do:
dpkg-divert --add --rename /usr/share/applications/firefox.desktop
In this case, that would be the overkill and less correct way of handing
the problem. A better way would be to put your own version of the
firefox.desktop into certain directories and that cause it to override
the system version of the config. Put them in
~/.local/share/applications/ to change an individual user and||
/usr/local/share/applications/ to effect every user on the system.

For the moment I've written a quick shortcut into my bash aliases file, but you got me looking at some ideas to create another firefox.desktop file that I can use to launch the application with the firejail parameters.
