Private data gathered in one private session won't + be available to any future private session either.</p> + +<h3>Recognizing a Private Window</h3> + +<p>To determine whether or not a window is in private browsing mode, have a + look at its title bar.

You can use the Back and Forward buttons as well as the Go + menu as usual.</li> + <li>Links will not be marked as visited when browsing in a private + window.</li> + <li>Bookmarks can be added in a private window in the same way as for a + non-private window. They will not be cleared once the private session + has ended.</li> +</ul> + +<h3>Browsing and other Histories</h3> + +<ul> + <li>Previously established Browsing History and Location Bar History will + be available to a private window, but new sites visited and locations + entered into the location bar will not be recorded and saved.</li> + <li>Files can be downloaded as usual, but no entries will be added to the + Download Manager. The downloaded files themselves will not be removed.</li> + <li>Saved Form and Search History will be available to a private window, + thus providing suggestions for form fields or searches. However, any + new items or search terms entered will not be recorded and saved.</li> +</ul> + +<h3>Cookies</h3> + +<ul> + <li>A private window can collect cookies from the sites it visits, but a + private window does not share cookies with a non-private window and vice + versa. For example, if you log into a website in a regular window, then + open a private window to continue, you likely will be asked to enter your + credentials again.</li> + <li>Cookies in a private session are accepted according to the settings, + but only retained for the duration of that session regardless of the + lifetime allowed in a non-private window.</li> + <li>Existing exceptions to the cookie policy will be honored in private + windows, and any new exceptions you create will be retained after the + private session has ended.</li> +</ul> + +<h3>Cached and Offline Content</h3> + +<ul> + <li>While a private window can use the memory cache for performance, it is + not permitted to access the disk cache regardless of the settings for a + non-private window. Thus, no cached content will be available after + restarting &brandShortName;.</li> + <li>A private window cannot use any stored offline content deposited by + websites. Thus, you will not be able to use web applications while being + offline, even if they have already stored offline content locally.</li> +</ul> + +<h3>Passwords and Authenticated Sessions</h3> + +<ul> + <li>No new passwords will be stored in the Password Manager when entered + in a private window.</li> + <li>Authenticated sessions do not carry over from a non-private to a private + window. Thus, you cannot continue a session started in a non-private window + in a private window or vice versa.</li> +</ul> + +<h3>Preferences and Permissions</h3> + +<ul> + <li>Any changes to settings and permissions made from a private window are + handled in the same way as from a non-private window and retained after + the private session has ended.</li> + <li>Per-site preferences such as zoom levels or download locations are + observed in a private window.
