(Disclaimer, I just tested it on my Ubuntu 20.04 machine with Firefox 
Nightly only and I know nothing about Citrix environment :) )

Hello Trever,

Give that Citrix does not work correctly with Firefox kiosk mode, I 
would workaround the issue by hiding the navigation bar with custom CSS 
injected in the user profile and if you can install extra packages on 
the user machines I would install xdotool (apt install xdotool) to force 
going into fullscreen at startup by simulating the F11 key. With a bash 
script I would do something like that:

```

target=/path/to/user/profile

cat >> $target/prefs.js <<EOL
user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true);
EOL

mkdir $target/chrome/
cat >> $target/chrome/userChrome.css <<EOL
#titlebar,
#nav-bar {
   visibility: collapse !important;
}
EOL

xdotool search --sync --onlyvisible --class "Firefox" windowactivate key 
F11 &
firefox --profile $target

```

If you are looking for a cross platform solution to the fullscreen 
issue, I think that deploying an autofullscrren extension is probably a 
better alternative.

Regards,

Pascal
