I have firefox that crashes every so often on my Ubuntu machine. I can't seem to kill the process when this happens. The process' name is /usr/lib/firefox/firefox

I've tried:

pkill -f firefox
pkill -9 firefox
kill <id>

I tried killing it in htop. I saw there were 3 sub processes there. I could kill two of them but not the plugin-container process.

I ran ps auxww and the process does not show a U to indicate that it's stuck. It does show a D however.
