Just a comment on Firefox, I've been doing a lot of Javascript lately
(I'm working on a sub windowing library and I must say firefox/mozilla
are render pigs. I attach more than 3 on move listeners to move with the
dragged pane and firefox becomes choppy crap soup. Opera and even
Internet Exploder can easily handle 50, and show a bit of lag when I
increase to 100 listener objects. Opera owns for speed though.
For debugging I use a custom data browser service that works in the 3
main browsers which has the nice advantage of seeing all the lovely
different field names that each browser uses *lol*.

And similar for debug echos:

I just wish all these damn browsers would work the same way for DHTML :(
Cheers,
Rob.
