Third Party Cookies Appear To Be Disabled
"Reset all zones to default level" leaves IE in a state where it blocks third-party cookies. If Internet Explorer disables third-party cookies by default, why does Stack Exchange use them?
And it looks like Firefox will soon block them too, and Safari already does.
If Stack Exchange requires the cookies, should it include instructions on how to "add an exception"?
