I have a Google App Script deployed as a Web application.

It was working normally, until this evening I discovered it would not load in Firefox or Chrome.

In Firefox I am getting this message;

Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://n-...-0lu-script.googleusercontent.com’) does not match the recipient window’s origin (‘https://script.google.com’). Removed part of URL

The app is deployed: (Executing as myself, and is Accessible for anyone, even anonymous).

I thought the issue might be with LastPass as mentioned here, but I have disabled LastPass in both browsers and the issue persists.

I'm not sure if this is a bug or a feature, but web apps starting in Chrome 60 may need to be set to XFameOptionsMode.ALLOWALL. I have a long running web app that just broke. Setting this worked.
