sudo kill -KILL

I do enjoy killing a runaway process. Or even if it isn't running away, like Firefox.

I am annoyed when someone leaves Firefox running with 15 tabs, nine of which are looking coupons and discounts for Fry's or some online outlet. I don't mind that, but I do mind those sites using process-intensive Flash advertisements. Orbitz is among the worst offenders.

It's probably the reason why the iPhone Safari doesn't run Flash, not only is there no need for it, but if there was, its usefulness decreases exponentially with every flashing banner telling me to shoot the duck.

So, I kill the process on Mac using "sudo kill -KILL" and its PID number.

I could also have used "sudo kill -STOP" to stop/suspend the process rather than kill it, and resume it later with "sudo kill -CONT".

Or maybe I'll install a Flash blocker, which gives you the freedom to choose when to enable it (such as when you want to play a game).
