• If Firefox doesn't open automatically, firefox -p default must be ran the first time Firefox is started after this command

ls '/tmp/profiles.ini' '/tmp/user.js' && pkill -f 'firefox' && rm -Rfv ~/'.mozilla' && sync && mkdir -p ~/'.mozilla/firefox/'$USER && mv '/tmp/profiles.ini' ~/'.mozilla/firefox/profiles.ini' && mv '/tmp/user.js' ~/'.mozilla/firefox/'$USER'/user.js' && sync && cat ~/'.mozilla/firefox/profiles.ini' | grep $USER && cat ~/'.mozilla/firefox/'$USER'/user.js' | grep 'Custom Stuff' && sleep '1' && sync || firefox -p 'default'
