MutationObserver wrapper to wait for the specified CSS selector.

setMutationHandler(document, '.container p.some-child', function(observer, nodes) {
    // single node:
    nodes[0].remove();

    // or multiple nodes:
    [].forEach.call(nodes, function(node) {
        node.style.display = 'none';
    });

    //observer.disconnect(); // disconnect the observer, this is useful for one-time jobs
    return true; // continue enumerating current batch of mutations
});

You may want to make your userscript run at document-start to catch the mutations during page load:

..............
// @run-at        document-start
..............
// ==/UserScript==
