Incognito (also called “Private Browsing” in Mozilla Firefox and Safari) is a mode you use to keep your search queries and browsing history secret. In Incognito mode, the browser doesn't save your passwords, autofill data, search queries, browsing history, or the pages you visit. However, changes to settings, downloaded files, and bookmarks are saved.
If you use Incognito mode, your browsing history and other data are inaccessible to site owners, who collect data for marketing purposes, and other people that may use your computer.
Information about your activities remains available to the internet provider (if they use DPI), the administrator of the local network through which you access the internet, and the administrator of the site where you enter personal data.
To enable private mode, use the instructions for your browser.
