Private Browsing doesn't make you anonymous on the Internet. Your Internet service provider, employer, or the sites themselves can still track what pages you visit. Private Browsing also doesn't protect you from keyloggers or spyware that may be installed on your computer.
Not having cookies means you’ll have to re-log into your favorite sites and re-enable the extensions you want to use one by one. But did you know that there’s a way for you to browse privately in Google Chrome but still stay signed into all your sites and have access to your extensions?
