    Hi,
    it's all linked to enhancement of the browsers security stuff (specially Chrome and Edge); apparently, the old implement sill works in FF.
    After getting help, the best practice to embed Url endpoints into iFrames is to follow this post from you guys : https://docs.microsoft.com/en-us/aspnet/samesite/system-web-samesite

    In fact, I just had to add the last line to make it work:
    HttpContext.Response.Cookies.Append(
    CookieRequestCultureProvider.DefaultCookieName,
    CookieRequestCultureProvider.MakeCookieValue(
    new RequestCulture(culture)),
    new CookieOptions() { SameSite = SameSiteMode.None, Secure = true} );

    Hopes it will help people with same issue.
    Txs
    Best Regards
