Sorry, word play -- Lookout Unimpressed == my name for Outlook Express,
the undeserved popular email client.  ;-)  You have to look out, because
it screws up all the time (using OE is like stepping in dog poop on
purpose), and that leaves me very unimpressed.  ;-)  Last time, I
deleted all text in email, yet OE inserted some random portion of the
text which had been deleted, which was not in the message editor when I
typed CTRL-enter (key combo for SEND button).  OE does this a lot and
pisses me off.  In some time I'll put all emails into MySQL and run a
web based mailer.

The other thing, I was sick in the hospital with a fever and very weak,
for 7 days.  I was poked,  stabbed, prodded, squeezed, chilled, drugged,
scanned, and otherwise molested as dictated by standard practice of
invasive western medicine.  I got back yesterday with no answers about
why I got sick or in exactly what way I got sick.  Most hospital people
maybe use a computer for 30 seconds once every month or two months.
They won't ever understand how seven days feels like suffocation of the
mind with the brain rotting out from lack of use, just staring at the
walls and ceiling, or worse, CNN.  ;-)

NO NO NO!!!  I AM NOT ANGRY!!!  YOU IDIOT!!!  ;-)  Joking.  :-)

Yes!  It takes time to sit and try things.  I am still a bit weak and
get tired, so must lay down.  I'm also a bit slow sometimes even when
I'm fast.  ;-)  I want to see the same things, think about the possible
causes, and try and reduce it to a single line or 2-3 lines of code that
can easily be commented or wrapped inside an "if ( flag )" or "switch
( flag )" where flag is a radio button.  So I can quickly turn on and
off any one of several options, to see how they compare in an example
page in different browsers.

5000 - 10000 s == 1.39 - 2.78 h?  Did you mean ms?

6ms is pretty good.  150+ ms is not great, but hey, it's JavaScript,
anything less than 5000ms is pretty good in JavaScript.  ;-)

Not too familiar with the current Mozilla events quirks.

I'm a fan of giving people (especially programmers) many options.  Some
people believe everyone should have few options, because it makes the
coding easier.  I'd say an option for automatic detection (based on some
half-baked algorithm which may or may not work right), and an option for
manually on or off, per object.  Maybe a single flag with three states:
[ auto | on | off ] with default off.
