IE9 -- First time showed "Hide Superfooter". I selected Hide Sooperfooter and it did, as expected. Now, after closing and re-opening IE9, I always see "Show Superfooter", never "Hide Sooperfooter". When I click on "Show Sooperfooter, it does not show the superfooter. It stays hidden. But continues to show "Show Sooperfooter". This happens both logged in and logged out. I can never see the sooperfooter.
IE9-EDIT: Okay, I figured this one out. I had enabled "Settings | Safety | Tracking Protection. When I turned that off it started working again "as advertised". Must have something to do with "doubleclick.net", etc.
Google Chrome -- Will hide the sooperfooter when I click on it. And toggle back and forth, as expected. But after closing Google Chrome, the next time it always shows the sooperfooter (doesn't save the setting). I have to click on Hide Sooperfooter each time after restarting Google Chrome. Tested logged and logged out for this test.
Safari -- Works as advertised. Logged in or out for this test.
