Hi, The "New Private Window" feature is certainly more practical in many situations, but unfortunately it does not seem to cover the following case: when doing online banking, the session has to be launched by an external application on a USB key ("UBS Access Key"). The banking login screen opens in the default browser (Firefox of course!), but unfortunately it appears in the main (non-private) Firefox window and its impossible to copy or move the link over to the private window. Apparently the external application establishes a connection to the main window, which cannot be moved or restarted in the private window. For this reason, I really appreciated the former private browsing mode of Firefox, which was not available in any other browser. And the fact that no other public browsing window was visible at the same time gave a better impression of security (I'm not sure if that impression was justified, though). -Jarle
