IE8 RC1: Privacy
Privacy and security have been a big focus for the IE8 team, and RC1 reflects that. The InPrivate Blocking feature debuted during the beta phase is now beefed up and renamed InPrivate Filtering. Its basic purpose remains the same -- it lets you monitor and control how Web sites share data about browsing history with other sites. In IE8 Beta 2, however, the feature would only operate when the so-called "porn mode," InPrivate Browsing, was activated. In RC1, you can turn it on and off at will, completely independent of the InPrivate Browsing setting.
