I am using Firefox as my browser and have it open Yahoo . With the main Yahoo screen up I want to open the web site for USAA.COM . I enter USAA and click on enter and get the error message "403 Forbidden". This happens for any other web site I'm trying to access. However, if I enter USAA.com in the upper window(mozilla.com) as http:/usaa.com and click on enter I get the USAA web site. What is going on between Yahoo, Firefox and the USAA web site? I did not have this problem with entering a web site I wanted in Yahoo until a month ago. I rebooted my system to a prior date (August 6th) and I found out how to navigate to a web site using the mozilla.com. The 430 error message still comes up when I try to navigate to a web site using the Yahoo bar.
