What is the PID of firefox process
 

In the event that firefox crashes, how do I find its PID?

If I only wish to close SOME tabs of firefox only, is it possible?

2. Not that I am aware of.

to get the PID:

Firefox is good about crash recovery, so if you have one tab that is causing trouble, kill firefox, and when you start it back up, uncheck the tab that was crashing.

If your only reason for wanting the pid is to kill the process, have a look at pkill/pgrep (I know this is not what you asked for, but it sounds as if it might be what you want).

Assuming you mean you want to close some tabs by killing off processes then no, that's not possible. Firefox does not run each tab as a separate process. It's one of those things that keeps coming up in lists of way Firefox could be improved.

ps stands for process

what does auwx stand for? It isnt in the man pages.

auwx is four separate options to the ps command. Each one of these is explained in the man page for ps.
