Firefox 30.0 no longer displays Yahoo on my computer running Windows XP (I do know that XP is no longer supported by Microsoft), nor on my IPAD running IOS 7.1.1, however the IPAD does display a working Yahoo Mail that receives and sends email satisfactorily. When asked to go to Yahoo, both computers display only a blank white screen with no graphics and with the Yahoo options listed in blue down the left margin: “Home” “Mail” “News” etc. When I click on “Mail,” it also displays my login name and address, but no messages. At the bottom of the screen the following is displayed: “Your screen elements are hidden from view. Press Esc or move pointer to the center of the screen to return to Mail. Press Esc or move pointer here to return to Mail. by on by Wine Discover something new.” Pressing Esc or moving the cursor has no effect. Firefox displays other websites properly and they work correctly. I have “reset” Yahoo and it now starts with the “Mozillla Firefox Start Page” instead of Yahoo as I want. I have also scanned my computer with Norton Internet Security for malware with none reported, and I have deleted and reinstalled Firefox with no improvement. Any help will be greatly appreciated.
