I think you mean nonresponsive, but I love the comment that
firefox/iceweasel is irresponsible. Perhaps its web designers who are
irresponsible.
LOL :)
First I experiment it with swiftfox, then I used Firefox (iceweasel) 2 and
the problem didn't go out. Then I switch to iceweasel 3 from experimental,
and I see this again.
I don't know how can I debug this problem. iceweasel take high % cpu during
the time it is irresponsible.
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.

But I think this strace doesn't give any clue.
I've never needed to learn how to read strace output.
Somebody with the same problem ? Any workarround ?
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 didn't install any plugin recently (only tamper data and developer
extension installed on my iceweasel)
I don't know what they do.
Good luck.
