You can have you cake and eat it too, just do:
dpkg-divert --add --no-rename /usr/share/applications/firefox.desktop
That will tell the packaging system to write any future version of
/usr/share/applications/firefox.desktop file to
/usr/share/applications/firefox.desktop.distrib instead so your local
changes won't be over written... and if you find that stuff is acting
weird in the future you can look in
/usr/share/applications/firefox.desktop.distrib and see if anything has
changed, and apply it to your locally changed version.

Success - I could not get any farther than what I posted the other
day using ~./local/share/applications/sandfox.desktop, but I achieved
100% success by editing /usr/share/applications/firefox.desktop.
Under the main {Desktop Entry] I appended "sandbox" to the Actions
parameter and then created a new [Desktop Action sandbox] submenu with
the lines:
[Desktop Action sandbox]
Name=Open in a sandbox
Exec=firejail --apparmor --private --dns=89.233.43.71 --net=eno1
--netfilter=/etc/firejail/nolocal.net <http://nolocal.net> --seccomp
firefox -no-remote
Now if I right click on Firefox I have "Open in a new window", "Open
in a new private window" and "Open in a sandbox". A quick "firejail
--list" confirms firefox is running with the full parameter string.
Yes, I'll have to add it every time Firefox updates, but for now I'm
willing to live with that. Gives me motivation to look into John's
suggestion of learning to patch the file.
Also found that my firejail-profile package was corrupted and that is
why I could not get --net= to work. Purged and reinstalled the package
which solved that problem.

That's what we are talking about. You can put your own
firefox.desktop file in ~/.local/share/applications/ and it will
supersede the package installed version of the file. I've found
just about everything in linux has a similar directory hierarchy
so you have control over a complete system and/or individual
program by putting alternative versions of config files in their
proper places.
According to the spec
(https://specifications.freedesktop.org/desktop-entry-spec/latest/index.html
<https://specifications.freedesktop.org/desktop-entry-spec/latest/index.html>)
the order that the .desktop files are searched for is in
$XDG_DATA_DIRS and the first one found is used.

You know, I fscking hate this between distros, but for arch on
mine, it's /usr/share/applications/firefox.desktop, and every
time I update it resets to defaults I hate. I keep a copy of
firefox.desktop as I need a menu to create a "choose profile"
menu for firefox when I need many profiles for different
customers, all with their own needs like different google and
microsith profiles for orfice365. Make sure you're hitting the
right file for the distro as different from deb/ubuntu/mint.
I'd say copy a working entry outside where you find the *.desktop
files, and just replace what works in a remote location to
upgrade when your dist. Firefox is the only thing to overwrite
and piss me off every time that I know to copy this when I
update. I normally just right click and do "Choose profile" for
firefox for the plethora of profiles, adding that option to my
firefox.desktop file, but apparently I'm the only person to do
this, so shenanigans needed. Same as yours I presume. Start
with a working one at least.
I need to play with this some, as I'd love to relaunch my 6-7
firefox profiles automatically, and not screw with my options to
launch manually. I'm sure there are easier ways to do this
normally, but I'm lazy to do so. /me shrugs

Thank you. The original goal was to add it to the menu in Pop
OS. I'll look again, but don't recall seeing it after I
created it in ~/.local/share/applications. Do I need to use
"--register-app" to add it, or should it just show up?

A desktop file is standardized configuration file for
Linux desktops that describe how to represent a program
in the menus (complete with multiple language support),
and how to launch it. So you can't just launch it
directly because it doesn't mean anything to the command
line. It should however be showing up in your menus now
and so you can put it in your favorites and easily launch
it that way.
That being cause, you can kinda turn it into an
executable by adding something like the following to the
very top of the desktop file:
#!/usr/bin/kioclient5 exec
That will tell the system to execute the desktop file
with kioclient... of course you need to be running KDE
for that to work correctly. I'm not sure what the GNOME
equivalent of that command is.
Personally I would just pretty alt+F2 or alt+space may
work as well and just start to type "Sandboxed Web
Browser" and you may only have to type Sand or so before
you can press enter and have it launch.
Alternatives to starting it from the command line:
Create a file called sandfox in /usr/local/bin/ and put
the following into it.
#!/bin/bash
/usr/bin/firejail --apparmor firefox $@
Then set it to be executable and then you can execute
sandfox from anywhere.
You could also set and alias with:
alias sandfox="/usr/bin/firejail --apparmor firefox"
That will allow you to type sandfox and internally it
will replace that with "/usr/bin/firejail --apparmor
firefox". That should also work in most places equally
well, but only for your username.
That's a one shot way of making that available. If you
want it to be permanent you'll need to add that line to
your .bashrc file with:
echo alias sandfox='"/usr/bin/firejail --apparmor
firefox"' >>~/.bashrc
I can't remember what your original goals were, so I hope
the above isn't completely shooting the dark.

I took Brian's recommendation and created a file in

Contents of that file are:

Encoding=UTF-8

Exec=/usr/bin/firejail --apparmor firefox
Name=Sandboxed Web Browser
Terminal=false
I have it set to executable but when i try to run it
"./sandfox.desktop" I get the error:
./sandfox.desktop: line 1: [Desktop: command not found
./sandfox.desktop: line 5: --apparmor: command not found
./sandfox.desktop: line 6: Web: command not found
Is my file misconfigured or what do I not have correct?

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.
