Hi Garry,

Just a bit more info that may help, your URL

http://355.vze.com/ListenPage.htm

responds to a wget with an Error 404, i.e. it has no DNS. The reason you do not see the error is because Firefox ignores it and loads the embedded frame page

http://websiterni.zapto.org/355/ListenPage.htm

This page loads perfectly in Chrome et al, but the first URL doesn't. I hope that is helpful, and I appreciate it works for most people, all I can suggest is that there is a DNS issue with the subdomain 355.vze.com I won't comment further on it as most browsers with default settings will not be affected, it's only those with enhanced security settings activated.
