childNodes is a list, not a function - some browsers are confused about
that:

var ch = container1.childNodes[0].id;

Are you getting an error in the console?

Why it could work in Safary I don't know,
but why it doesn't work in FF :
because the first chidNode in FF is an invisible text node (without id)
and anyway ... it is :

ch = container1.childNodes[0];

He can also have a look in Firefox's DOM inspector ( #text )

test :
======
ch = container1.childNodes[0];
alert(ch.nodeName);

Actually the absence of id wouldn't cause a problem for this,
FF would show 'undefined' in the alert box. Round brackets
as opposed to square definitely are the culprit.

Depends a lot on what container1 is, a text node isn't always
the first child.

But it's always a good idea to learn to use the tools that are
there to make the job easier.
