You should be able to access the element; if you couldn't you'd most likely be getting something akin to a null pointer exception.

I looked in the Mozilla DOM documentation, but couldn't find an "element.value" attribute. The closest I could find is the "element.nodeValue," which returns null for all elements, and has no effect when set.

Rather than trying to assign the value directly to the node I prune all the children of the element, and then append a new new text node containing the updated label. Check out the following methods...

- element.hasChildNodes
- element.firstChild
- element.removeChild
- element.appendChild
- document.createTextNode

I suspect there's an easier way to achieve this.

I'm not sure what placing the Javascript in the sidebar xul will do; it sounds plausible that it's only run when the sidebar is open?
