I think you mean nonresponsive, but I love the comment that
firefox/iceweasel is irresponsible. Perhaps its web designers who are
irresponsible.
LOL :)

Run top in an xterm/rxvt/whatever with a 0.25 second delay. You could
even run it in batch mode for 100 repititions and tee it to a file for
checking after the 4-second event. Look for not just the CPU load for
that process, but CPU and IO load globally.

I've never needed to learn how to read strace output.

I'm on dialup. Its normal for me to wait for iceweasel to grab a page
and display it. Sure it runs the CPU to 0% idle at times. That's the
whole reason I bought by new computer: Athlon64 3800+ with 1 GB ram:
because iceweasel/firefox uses a lot of resources. Most everything else
in my life can run just fine on my 486 or P-II.

I don't know what they do.
Good luck.
