Google chrome provides a feature which allows users to browse privately, which means users browser histories , downloaded histories or web sites cookies are not maintained after the browsing session. For more information check the below video
To access this feature click on the Google Chrome Customize menu and select New incognito window. Alternatively use the keyboard shortcut Ctrl + Shift + N
This would launch the incognito browser window. Incognito browsing does not store browser related information on your local PC i.e you do not have to manually clear browsing history. But still you need to be careful while using secured login credentials, credit card information on any web site browsed using incognito window. Using incognito window does not mean that you will not be caught by the firewall in your organisation.
