AT & T notified me that sbcglobal.net will be retired on 01 Oct, 2010. I downloaded Firefox 3.6 to use as my new browser. I can still currently access my sbcglobal.net emails by clicking the Mozilla desktop icon and the drop-down menu of "Get email from Yahoo!". Will my prior saved emails that I have in Folders still be accessible after 01 Oct when sbcglobal retires? [I cannot get that info off the AT &T website and after waiting 30 minutes on their HELP phone number--I gave up.] Do I need to actively do something to transfer those Folders to Firefox? [I'm not sure I have Thunderbird properly downloaded.]
