I'm getting pagina non trovato, being redirected to <http://jump.xoom.virgilio.it/jump.htm>. Safari Mac redirects to the error page but Firefox Mac won't even read the html, huh? You see: <!-- saved from url=(0022)http://internet.e-mail --><html><head><title>SPAZIO WEB - Errore</title> Mac IE does the same.
http://xoomer.virgilio.it/n.waugh/ works.
http://art.supereva.it/alanfffo.superdada/secretfluxus/index.html is very very slow and only sort of works. That must be the one you mean.... <FRAMESET> tag put in by supereva.it seems to be the culprit as it's not done right at all, generating many syntax errors.
Install http://texturizer.net/firefox/extensions/#webdeveloper for Firefox and try some html validation. You'll see some other things that are unpleasant and have little to do with your pages themselves.
Too bad http://www.1and1.com is no longer free. But it's cheap. Ditto a few other places.
http://alanfffo.ehost.com/ works and looks good. Can you move everything there?
