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]; > Are you getting an error in the console?

Round brackets as opposed to square definitely are the culprit. > > Are you getting an error in the console? > He can also have a look in Firefox's DOM inspector ( #text ) 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. --- Geoff
