cannot kill -9 firefox 70.0.1 on 12.1

[Tomasz CEDRO]

Hello world :-)

I have strange problems with Firefox 70.0.1 on 12.1 AMD64. It
sometimes hangs my GUI (enlightenment), takes CPU and Memory. I can
kill a window, then unable to start new window because "firefox is
already running". I am unable to kill it even -9 as root :-(

What happened with old good kill -9 it does not seem to work anymore?

Did anyone experience similar problems?

Tomek
