AppleScript saved as application doesn't execute whole script when argument is passed I save the following AppleScript as application, to open Firefox in full screen and without the menu bar:

tell application "Firefox" to activate
delay 0.8
do shell script "lsappinfo setinfo -app Firefox ApplicationType=UIElement"
tell application "System Events" to tell process "Firefox" to set value of attribute "AXFullScreen" of last window to true


And execute it as:

open -a "Firefox Full Screen"


This works as expected, Firefox is opened, goes full screen, without the menu bar. The problem is when I try to call open with a URL:

open -a "Firefox Full Screen" "https://google.com"


This still opens Firefox, with the given URL in a new tab, but it doesn't execute the lines after delay 0.8, so it doesn't open in full screen. I don't understand why this happens and how to fix it.

I know those lines are not executed because the system doesn't warn that I need to add the application as an accessibility exception (when I don't have one added/enabled). It always warns if I don't pass the URL (and don't have an exception added/enabled).

EDIT 1

I also tried to execute the following version with open -a "Firefox Full Screen", open -a "Firefox Full Screen" "https://google.com", open -a "Firefox Full Screen" --args "https://google.com" and it's worse given that it doesn't execute the last lines in any case:

on run argv
    tell application "Firefox"
        activate
        repeat with arg in argv
            open location (arg as text)
        end repeat
    end tell
    delay 0.8
    do shell script "lsappinfo setinfo -app Firefox ApplicationType=UIElement"
    tell application "System Events" to tell process "Firefox" to set value of attribute "AXFullScreen" of last window to true
end run


EDIT 2

It seems the problem is related with https://stackoverflow.com/questions/14419700.
It looks like passing arguments to an AppleScript saved as an application has become broken at some point. I accomplished my task by using Automator to create an equivalent new Application that makes use of an Action &gt; Utilities &gt; Run Shell Script:

open -a Firefox
sleep 1
lsappinfo setinfo -app Firefox ApplicationType=UIElement
osascript -e 'tell application "System Events" to tell process "Firefox" to set value of attribute "AXFullScreen" of first window to true'
sleep 0.5
for f in "$@"; do open -a Firefox "$f"; done


I set the shell script Shell: to /bin/sh and Pass input: to as arguments, save it as "Firefox Full Screen" in /Applications, change its icon as explained here and add it as an exception in System Preferences &gt; Security &amp; Privacy &gt; Privacy Tab &gt; Accessibility.

I then can run any of the following and it works as expected:


open -a "Firefox Full Screen"
open -a "Firefox Full Screen" --args "https://google.com"
open -a "Firefox Full Screen" --args "https://google.com" "https://twitter.com"


I'm using this coupled with the following userChrome.css to both evade a well known issue with the macOS menu bar on full screen applications and another long standing address bar and tab auto-hide bug that Firefox have with macOS native full screen.

userChrome.css

#navigator-toolbox[inFullscreen] {
    position: relative;
    z-index: 1;
    height: 3px;
    margin-bottom: -3px;
    opacity: 0;
    overflow: hidden;
}

#navigator-toolbox[inFullscreen]:hover {
    height: auto;
    margin-bottom: 0px;
    opacity: 1;
    overflow: show;
}

#content-deck[inFullscreen]{
    position:relative;
    z-index: 0;
}

TIP


Firefox, by default, does not have any issue on Linux or Windows to auto-hide address bar and tabs in full screen as expected. With that said, I grabbed this userChrome.css from my ArchLinux setup. I use it on i3 and sway tiling window managers, with all the [inFullscreen] removed, to get address bar and tabs to auto-hide in normal bordless windows.
