Hey, hopefully someone can help me in regards to my yahoo email account. When I try to sign in, a page is brought up that says: Unable to connect Firefox can't establish a connection to the server at us.f545.mail.yahoo.com. * The site could 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. However, I have two yahoo email accounts. The second one opens with no problem. I don't understand. Why can't I open my current account, an account which is used daily? Thanks in advance.
