Web Containers will not load

Going to the svelte tutorial the "booting webcontainer" hangs at 20%.

The console shows:

Finally wanted to give Svelte a shot and well, same issue. Any fix for this?

Hello, I get the same behavior in Firefox 115 and 127

In the console I see Uncaught DOMException: The operation is insecure. _0x41422d https://httpslearnsveltedev-xfsn-4a7e5jbs.w-corp-staticblitz.com/iframe.main.70dbe416.js:4 _0x4727c0 https://httpslearnsveltedev-xfsn-4a7e5jbs.w-corp-staticblitz.com/iframe.main.70dbe416.js:4

The solution was to change the "Enhanced Tracking Protection" in the Privacy settings, it was set to custom and I changed it to Strict and the site works normally now.

Hope this helps somebody.
