How to override JS function from a firefox extension?
- by BruceBerry
Hello,
I am trying to intercept calls to document.write for all pages. Setting up the interception inside the page by injecting a script like
function overrideDocWrite() {
alert("Override called");
document.write = function(w) {
return function(s) {
alert("special dom");
w.call(this, wrapString(s));
};
}(document.write);
alert("Override finished");
}
is easy and works, but i would like my extension to setup the interception for each document object from inside the extension. I couldn't find a way to do this. I tried to listen for the "load" event and set up the interception there but it also fails. How do I hook calls to doc.write from an extension?
