`pkill -9 -f firefox` won't work, what can be a possible explanation? (social.fossware.space)
My friend was running firefox on linux mint, and it froze and he used xkill to kill firefox. But still it shows up in htop ps -aux. He tried to kill it multiple times but it didn’t work. See the pictures for explanation. We had to kill power to shutdown, even systemd can’t stop that process....
