var tabs = require("sdk/tabs");
var data = require("sdk/self").data;

var pageMod = require("sdk/page-mod");
pageMod.PageMod({
  include: "http://mydomain/x.html",
  contentScriptFile: data.url("listen.js")
});

self.port.on("myAddonMessage", function(myAddonMessagePayload) {
  console.log("working");
});

main.js doesn't have a self.port, content-scripts do. In main.js you instead need to use port with whatever initiated the content-script. E.g. the PageMod documentation has more.

var data = require("sdk/self").data;

var pageMod = require("sdk/page-mod");
pageMod.PageMod({
  include: "http://mydomain/x.html",
  contentScriptFile: data.url("listen.js"),
  onAttach: function(worker) {
    worker.port.on("myAddonMessage", function(myAddonMessagePayload) {
      console.log("working");
    });
  }
});
