Compare Private Browsing Features in Different Browsers
Browsing history is used by the browser to enhance your experience on the Internet. When the browser remembers a website you previously visited or the username and password for your favorite web site, this information is considered your history.
However, there may be times when you do not want other users of your computer to see or access such information. For example, if a friend or family member shares your computer, you might prefer for them not to be able to see what websites you've visited or what files you've downloaded.
Different browser has slightly different features of private browsing.
In IE, it's called "InPrivate Browsing". InPrivate Browsing enables you to surf the web without leaving a trail in Internet Explorer.
You can start InPrivate Browsing from the New Tab page, or by pressing CTRL+ALT+P.
When you start InPrivate Browsing, Internet Explorer opens a new window. The protection that InPrivate Browsing provides is only in effect during the time that you use that window. You can open as many tabs as you want in that window, and they will all be protected by InPrivate Browsing. However, if you open another browser window, that window will not be protected by InPrivate Browsing.
To end your InPrivate Browsing session, close the browser window.
InPrivate doesn't clear any history or information about toolbars or browser extensions that is stored on your computer. Internet Explorer disables all toolbars and extensions by default in an InPrivate Browsing window.
InPrivate Browsing helps prevent Internet Explorer from storing data about your browsing session. IE also provide InPrivate Filtering, which helps prevent website content providers from collecting information about sites you visit.
