I can sign on but I can't view my emails. When I try to it gives me a error page. Which says :

Unable to connect

Firefox can't establish a connection to the server at us.f543.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.

But I can sign on my other email accounts. Someone please help me!

The server is down. Try their back up server instead: http://us.m.yahoo.com/

It will give you e-mail in basic text form.

Yahoo problems. Some get thru, some don't. Thery're working on it.
