If they have just changed the oncontextmenu handler (which is the most straightforward way to do it), then you can remove their override thus:

window.oncontextmenu = null;

Otherwise, if it is attached to individual elements, you can get all the page's elements, and then remove the handler on each one:

var elements = document.getElementsByTagName("*");
for(var id = 0; id < elements.length; ++id) { elements[id].oncontextmenu = null; }

Or, it seems you can turn off such scripts; via an extension in Chrome or an option in Firefox - in the advanced box for javascript options, switch off 'Disable or replace context menus'.
