Not working

[nothingnesses]

Hi. I am using Firefox 61.0.2 on Void Linux and have installed pyllyukko/user.js as a system-wide autoconfig, but it doesn't seem to be changing Firefox's settings in about:config. I installed it using the following script for the ion shell:

#	make pyllyukko directory if it doesn't exist already
fn mkdir_pyllyukko dir_pyllyukko
	if not exists -d $dir_pyllyukko
		echo Creating \"$dir_pyllyukko\"...
		mkdir -p $dir_pyllyukko
		echo
	end
end

#	clone or pull user.js
fn git_user_js dir_user_js dir_pyllyukko
	if not exists -d $dir_user_js
		git -C $dir_pyllyukko clone https://github.com/pyllyukko/user.js.git
	else
		echo Checking if \"$dir_user_js\" is up to date...
		git -C $dir_user_js pull
	end
	echo
end

#	make systemwide_user.js
fn make_systemwide_user_js dir_user_js
	make -C $dir_user_js systemwide_user.js
#	add "//" to top as suggested in readme, not needed though as it already has one
#	sed -i '1i\/\/' $dir_user_js/systemwide_user.js
	echo
end

#	make firefox directory if it doesn't exist already
fn mkdir_firefox dir_firefox
	if not exists -d $dir_firefox
#		if not exists -d /etc/firefox
		echo Creating \"$dir_firefox\"...
		sudo mkdir -p $dir_firefox
#		sudo mkdir -p /etc/firefox
		echo
	end
end

#	symbolically link systemwide_user.js
fn ln_systemwide_user_js dir_firefox dir_user_js
	if not exists -f $dir_firefox/mozilla.cfg
#	if not exists -f /etc/firefox/syspref.js

		echo Linking \"$dir_user_js/systemwide_user.js\" to \"$dir_firefox/mozilla.cfg\"
		sudo ln -s $dir_user_js/systemwide_user.js $dir_firefox/mozilla.cfg
#		sudo ln -s $dir_user_js/systemwide_user.js /etc/firefox/syspref.js
		echo
	end
end

#	make preferences directory if it doesn't exist already
fn mkdir_preferences dir_preferences
	if not exists -d $dir_preferences
		echo Creating \"$dir_preferences\"...
		sudo mkdir -p $dir_preferences
		echo
	end
end

#	make autoconfig.js if it doesn't exist already
fn make_autoconfig_js dir_preferences
	if not exists -f $dir_preferences/autoconfig.js
		echo "pref(\"general.config.filename\", \"mozilla.cfg\");" | sudo tee $dir_preferences/autoconfig.js
		echo "pref(\"general.config.obscure_value\", 0);" | sudo tee -a $dir_preferences/autoconfig.js
		echo
	end
end

#	update pyllyukko/user.js
fn update_pyllyukko dir_pyllyukko dir_user_js dir_firefox dir_preferences
	mkdir_pyllyukko $dir_pyllyukko
	git_user_js $dir_user_js $dir_pyllyukko
	make_systemwide_user_js $dir_user_js
	mkdir_firefox $dir_firefox
	ln_systemwide_user_js $dir_firefox $dir_user_js
	mkdir_preferences $dir_preferences
	make_autoconfig_js $dir_preferences
end

#	main
fn main
	let dir_pyllyukko = "/data/github/pyllyukko"
	let dir_user_js = "$dir_pyllyukko/user.js"
	let dir_firefox = "/usr/lib/firefox"
	let dir_preferences = "$dir_firefox/browser/defaults/preferences"

	update_pyllyukko $dir_pyllyukko $dir_user_js $dir_firefox $dir_preferences
end

main

My script seems to have installed user.js correctly (as based on this documentation). It managed to create /usr/lib/firefox/browser/defaults/preferences/autoconfig.js containing:

pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0);

and also /usr/lib/firefox/mozilla.cfg which is a symlink to systemwide_user.js generated from the Makefile. Nonetheless, none of the settings in systemwide_user.js seems to have been applied when I check in about:config. I even tried using /usr/lib/firefox/defaults/pref instead of /usr/lib/firefox/browser/defaults/preferences, symlinking systemwide_user.js to /etc/firefox/syspref.js instead, and also deleting the Firefox profile (after every change I made), none of which solved the issue. As such, I'd really appreciate any help.

For what it's worth, I'm using a script to update and set pyllyukko/user.js as a system-wide autoconfig instead of just copying it manually as a single-user user.js as I want to change some of its default settings (using a user.js file later on), yet still be able to update it from the repo without git complaining of new changes I made causing conflicts or whatever, so if there is an easier way to do this (i.e., change settings and still be able to update it), please let me know. I feel like it could probably be done much simpler using a script that maybe pulls changes from the repo then rebases any changes i made automatically (is that the correct term?), but unfortunately I don't understand how to use git farther than cloning and pulling 😭 😂.

Similar issues were solved by appending the entries to the existing user.js
Is your script working on files and dirs that have proper permissions (done with chmod command)?
