} )
} )
});

observer.observe(document, {

What I mean is that to forbid auto-add '(2 new messages)' in the title from some site, instead of delete some element of a website.

If you want to forbid the auto adding, I think you need to redefine appendChild method of the parent node (it will work only if this element adding to parent by this method).

element.parentNode.appendChild = function(){}
