I'm having a problem. The number of "websites stored cookies or other data" keeps jumping around! First it shows 116, then jumps to 24, then jumps to 116, 117, then 15, then back to 24 again. Other numbers have been shown in a cycle, too. When I click on "details" the lists jumps around too. First listing many sites, then a few, then many again and so on. This is continuous. I tried "Remove All Website Data", but no luck. Any ideas? I've never had this problem before.
