I strongly suspect a better option would be to inject a <script> element
into the Facebook page, containing an alternate implementation of
MegaphoneHelper. (Presumably this alternate implementation would do
nothing, or perhaps at most log messages to the console.)
Something like this (untested, but resembling code I've written before):
var nodScript = document.createElement("script");
nodScript.innerHTML = "MegaphoneHelper = {};";
document.body.appendChild(nodScript);
document.body.removeChild(nodScript);
Try it and let us know how it works.
