A few dedicated Chrome and Firefox extensions can automatically activate the internet private browsing module.
But heads up, private browsing does not protect you from serious attacks, it will only ensure a better comfort level, as you will benefit from a little bit more privacy on the Internet.
How to permanently activate the private browsing mode when you are online? Here is your answer
For Google Chrome users it is recommended that you use the Ghost Incognito extension. This extension allows you to open some domain names you preset in the incongnito mode. In other words, it lets you choose which websites you want to browse privately.
For Firefox users, there is the “Open Links In private Browsing Mode” extension. All you have to do is to install it. Activation is made through a click on the link you want to open in private browsing mode.
