This is a nuisance, not a big problem, but it is weird.

Iceweasel (basically same thing as Firefox) is running, with a couple of windows open. Most of the time I can issue
ps -u myusername | grep fox
and I get a process number for, I think firefox-bin. Something about firefox, anyway.

But once in a while (like now), I'll need to kill Iceweasel because the sound is misbehaving, and ps -u myusername does not produce any lines containing "firefox". So there's no way to kill it! killall firefox-bin doesn't work either.

Like I said, weird. I tried ps -A and ps -e, but still no firefox listed. Also, top does not show any firefox process. How can this be?

Oh yes, I did check for processes with "ice" in the name also.

Thanks, LinuxQuestioners.

Iceweasel is a "wrapper package", nothing but 1 MB java* , etc.
and a link 'firefox-bin' to ../xulrunner-1.xx/xulrunner-stub.

'top' sometimes shows one relevant process = xulrunner-stub
Next time you start iceweasel the process can be named : firefox-bin.

'killall xulrunner-stub' or 'killall firefox-bin'
.. will kill iceweasel, I guess.
.....

Thanks, Mr-Bisquit and knudfl.

ps aux did show /usr/lib/iceweasel/firefox-bin -a iceweasel

and xulrunner-stub shows up in both top and ps -u myUserName
