I would appreciate help in troubleshooting and solving my problem of which the email transfer disruption network error is only one of the problems. I'm using Mozilla Firefox rather than Microsoft Explorer with Ixquick as my default Internet search engine. I have Juno as my email provider. I have the same features on a laptop via WiFi and my workstation. We have a new modem, and have had problems since the installation of the new modem. With each attempt to transfer my email, there is the following Mail Transfer Error message: "There were errors encountered during mail transmission. Mail transfer was disrupted by a network error." In searching the Internet using Ixquick, I encounter the following message(s): "Unable to connect" "Firefox can't establish a connection to the server at support.moxilla.org." "The site could not be temporarily unavailable or too busy. Try again in a few moments." "If you are unable to load any pages, check your computer's network connection." "If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web." "Try Again" Thank you for your time and efforts with this matter. Take care, Margo
