No way to enable cross-scripting in browser

[ezYakaEagle442]

in https://aksworkshop.io/#frontend it is mentionned :

Browse to the public hostname of the frontend and watch as the number of orders change
Once the Ingress is deployed, you should be able to access the frontend at http://frontend.[cluster_specific_dns_zone], for example http://frontend.52.255.217.198.nip.io
If it doesn’t work from the first trial, give it a few more minutes or try a different browser.

Note: you might need to enable cross-scripting in your browser; click on the shield icon on the address bar (for Chrome) and allow unsafe script to be executed.

But there is no more options in Edge, IE11 neither : https://blogs.windows.com/windowsexperience/2018/07/25/announcing-windows-10-insider-preview-build-17723-and-build-18204/

In Firefox neither :

I tried F12 in Edge :
SEC7120: [CORS] Le « ms-appx-web://microsoft.microsoftedge » d'origine n'a pas pu autoriser une ressource cross-origin font à « ms-appx-web:///assets/Fonts/BrowserMDL.ttf#Browser MDL2 Assets ».

or Dev bar in Firefox, no magic option to enable it :
