I figured out
my problem. I was trying to set the contextmenu attribute of a DOM
node to the ID of an element that had not been created yet.

My XPCOM object build a DOM structure on a
DocumentFragment then holds it for the chrome code to use. The chrome
take the DocumentFragment node and clones it into the toolbar. I know this seems
like a lot of work, but it's how it has to be done in my case.
Also, if I have the XPCOM code run, but turn off the chrome side, I
don't get this error. Does anybody know how an extension could
generate this and how to prevent it?
Thanks,
Jeremy
