Why [removed]void(0) is not working in Firefox

Question

Why is this simple link example not working in Firefox? It is working in IE and Chrome.
js fiddle sample
I am using windows XP. My Firefox version is 16.0.

Answer 1

My research for getItems() showed what in some situations this function is defined as native function. I don't know why. To avoid this trouble try to rename function getItems.

UPDATE:

As specified in comment by Boris Zbarsky this trouble can be also avoided when adding window. before getItems() (e.g. window.getItems()).
