In your ps output, there is no firefox command running. There is however a xulrunner-bin that is responsible for executing firefox.

By default, pgrep does not match patterns against command line arguments (that requires -f).

You can aways try
Code:
pkill -9 firefox

the -9 is a signal that tells the pkill command to be an aggressive kill. I would suggest looking at the different signals you can send to a process with kill or pkill by doing a
Code:
man pkill

or
Code:
man kill

The signal sent is irrelevant if there's no process to receive it.

In particular, pay attention to the semantics of 'pattern' and the -f option.

That explains why some of us have no problems pkilling Firefox and some do. You are using an older version of Firefox.

More modern versions of Firefox on Linux invoke a $LIBDIR/firefox/firefox executable and not xulrunner.
