When I open Firefox I do not navigate to the home page I had set. I go to an AT&T page and then I have to sign into the AT&T account. This started about 3 days ago. After I have been on the net for a while I get the massage"We noticed you may have signed in or signed out in another window. Click OK to reload your page." I then have to click on the message and then am redirected to the AT&T page that I have to log into to get back to the page I had set. I have tried, unsuccessfully, to reset my home page. Both by going to the tool bar and by dragging the icon of the home page to the home icon.
