I've owned my iPad (the one with the Retina display) for only a few days. Suddenly the Safari tabs won't close. Of course I know to tap on the little x near the left edge of the tab but that does nothing. I've powered down the iPad but when it comes back up Safari remembers all of the tabs and still refuses to close them. I'm desparate enough to just blow away Safari but I don't know how to do that either. (I found a post saying to make the icon wiggle and then tap the upper right corner but that did nothing.)
I've found many hits on the Internet about this Safari problem, but all have been for the non-iPad versions of Safari and have solutions which don't translate to the iPad.
