Configure your web browser to open an incognito window by default so that no browsing data is stored.
Whether you use Chrome or Firefox, you’ve probably used private browsing before. This mode allows you to use the web browser without any browsing data being stored.
If it requires you to reconnect each time to all your usual sites, private browsing has the great advantage of letting you browse without your browsing history, cookies, and other personal data being stored in the browser history. So, on your next visit, there is no risk of seeing advertising for the shoes that have been so desirable to you for several weeks.
Officially, opening a private browsing window is done when the browser is already open, from the main menu, or by using a keyboard shortcut Ctrl + Shift + P on Firefox, and Ctrl + Shift + N on Google Chrome. But it is perfectly possible to configure these two browsers so that they open an incognito window by default. Here’s how.
On Firefox
To configure Firefox to open an incognito window by default, click on the main menu and go to Browser Options.

Then access the Privacy and security options, and scroll through the settings until you reach those relating to History. In the drop-down menu dedicated to Retention rules, choose Never keep history.

Thus, Firefox will always use the same settings as the browser’s private browsing settings, ie no history will be kept.
On Google Chrome
Configuring Chrome to open an incognito window by default requires a little manipulation that is fairly simple to set up.
Open Chrome on your PC, right-click the icon in the taskbar, then right-click Google Chrome a second time to display the options menu and click Properties.

In the Property window of Google Chrome, in the Target line, place the mouse cursor at the end of the line after the last quotation mark, make a space, and add -incognito.
Validate by clicking on Apply then on OK.

Close all browser windows and restart it. Logically, Chrome should automatically open to an incognito window.
You can go back very easily by removing the space and the -incognito command as seen previously.
