There are between 11 and 12 occurrences (depending on which patches are installed) of createElementNS(XUL_NS, "xul:tagname") in HUDService.jsm. The xul: prefix is at best a no-op since we're specifying the namespace. We should remove them based on Dao's comment in: https://bugzilla.mozilla.org/show_bug.cgi?id=611795#c54
taking this as a follow-up to bug 662807.
