Everything was working fine under Win8Pro Release Preview and FF (17?)... Did full Win7Pro SP1 x64 install. Installed FF 18.0.1, no add-ons; all defaults except turned on "do not track" and changed cookie handling as described: Logging in to my Hotmail/Outlook.com account (MS upgraded me to Outlook.com in the middle of my troubleshooting) I can access my Hotmail People (Contacts) without difficulty. I change FF Options -> Privacy -> "Keep cookies until" from "they expire" to "ask every time." When I go to "Hotmail People", I click on "Allow" for every instance I'm asked to set or modify a cookie. The content of the "People" page (the contacts themselves) never loads. I just get the "please wait" circling-dots. I return to the Hotmail "Mail" page (which still works fine, except when addressing a message). I change FF Options -> Privacy -> "Keep cookies until" from "ask every time" to "they expire." When I go (back) to Hotmail People, the contacts load fine. Shouldn't the two scenarios be the same? I prefer to manually handle cookie handling, so this feature is important to me. Thanks! PS: With the exception of addressing in Mail; Mail, Calendar and SkyDrive all seem to work fine regardless of which cookie setting is used.
