Firefox Addon SDK message passing error

Question

Im trying to pass messages between a pageMod and a content script.

I use this code with the pageMod

var gmailPageMod = pageMod.PageMod({
            include: "https://mail.google.com/*",
            contentScriptWhen: "ready",
            contentScriptFile: [self.data.url('js/script.js')],
            contentStyleFile: [
                self.data.url("css/angular.min.css"),
                self.data.url("css/style.css")
            ],
            onAttach: function(worker) {
                try {
                    console.log("adding worker");
                    gmail_workers.push(worker);
                } catch (error) {
                    console.log("error", error);
                }

                worker.port.on("getTalentGamil_recipient_change", function(email) {
                    console.log(email);
                });
                try {
                    console.log("updating SS");
                    console.log(simpleStorage);
                    worker.port.emit("updateSimpleStorage", simpleStorage);
                } catch (error) {
                    console.log("error", error);
                }

            });

and in script.js

self.port.on("updateSimpleStorage", function(simpleStorage) {
    console.log('updateSimpleStorage from script.js', simpleStorage);
    var e = new CustomEvent('updateSimpleStorage', {
        'detail': simpleStorage
    });
    window.dispatchEvent(e);
});

However this gives me an error Message: [Exception... "Failure" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: <unknown filename> :: <TOP_LEVEL> :: line 0" data: no]

I dont understand why though? Because I think Im doing exactly whats being done here. I'd appreciate any help on the matter

Answer 1

I came across this and according to it, CustomEvents no longer work, so I used a roundabout message passing route with FF Addon SDK's native messaging to get my info across.
