I cannot connect to my earthlink email using Firefox ??? I can access through Safari and have talked with Earthlink. Also, ever since Firefox has changed format, the speed of my service has been diminished. What is going on???

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

Hey there Mr. Spock,
It sounds like you have done most of the troubleshooting in http://support.apple.com/kb/ts2972, and home sharing on one computer. I dont know if you have done this, but I would next check the Firewall settings with that article.
Troubleshooting Home Sharing
http://support.apple.com/kb/ts2972
5. Check Firewall settings
If you have a firewall enabled in your router or computer, make sure that the firewall is not blocking communication between your computers. Home Sharing uses TCP port 3689 and UDP port 5353 to communicate with shared iTunes libraries.
In addition, Apple TV and Mac computers will use port 123 to set the time automatically. Incorrect date and time on either the computer or Apple TV can cause errors for Home Sharing and connections in general.
If you are unsure whether your router has a firewall or the required ports open, test additional devices or another network to help isolate the issue. If the devices tested work on another home network, it is your router or network configuration.
For Mac OS X, you don't have to edit the port addresses, but make sure the firewall in Apple () menu > System Preferences > Security > Firewall are not set to:
Block all incoming connections
Allow only essential services
If you use another security/firewall software on your computer or router, follow this article or contact the manufacturer or check the documentation on how to open TCP ports 123 and 3689 as well as UDP ports 123 and 5353.
For more information on ports used by Apple products, see Well known TCP and UDP ports used by Apple software products.
Thank you for using Apple Support Communities.
Take care,
Sterling
