Firefox can't open Nuxt link

[cyrilf]

I'm using Firefox (131.0.2) on a private session with no extensions, when clicking on any link pointing to nuxt.com/**, I have an error.
It opens the panel and displays:

Blocked Page

An error occurred during a connection to nuxt.com. 

On the network tab I have a NS_ERROR_DOM_COEP_FAILED error.

Using Chrome, no error occurs.

After some investigation it seems that it's related to this file using credentialless on the iframe which is currently experimental and not supported on Firefox.
