Google Colaboratory ServiceWorker Error On Chrome / Vivaldi

Question

This is the same issue as this post: Google Colaboratory ServiceWorker Error On Chrome

...but I am using Vivaldi (1.15.1147.36 (Stable channel) (64-bit)) on ubuntu 18.04.

Upon opening a document, I am met with this: NotSupportedError: Failed to register a ServiceWorker: The user denied permission to use Service Worker.

My question, specifically: Is it possible to make this work WITHOUT enabling all 3rd-party cookies? (The only Vivaldi setting I see is a check box for all 3PC's or none.)

Thanks, everyone.

Answer 1

From the FAQ:

Why prompt to enable third-party cookies?

Colaboratory uses HTML iframes and service workers hosted on separate origins in order to display rich outputs securely. Browsers require enabling third-party cookies to use the service workers within iframes. An alternative to enabling third-party cookies for all sites is to whitelist the following hostname in your browser settings: googleusercontent.com.
