I have to use att.net classic mail instead of att.net all-new mail with Firefox. The message says I need to have a Firefox version 2.0 or higher to use all-new mail. I am using Firefox version 3.6.12. I am using Windows XP.

You need to reset your User-agent string (identifies the browser you are using). Yours is set as:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.12) Gecko/20101026 NET_mmhpset ( .NET CLR 3.5.30729)

Your User-agent is identifying itself as NET_mmhpset rather than Firefox. For details of how to reset it see websites or add-ons incorrectly report incompatible browser.

To see your User-agent, Help > About Mozilla Firefox, look at last 2-3 lines.
