Regarding internet browsing, it should be known that the data relating to the web pages you visit does not disappear when you close your browser or turn off your computer. All the history of the websites visited is saved for a certain period.
Furthermore, when you surf the internet, they exchange data with the sites which capture statistical information on visits.
Whatever computer you use, when you browse websites, they exchange data with other computers (a website actually resides on a server).
The browser with which you visit a website, receives the data to load the pages or applications while the site takes some information from the computer and releases a cookie, i.e. a simple text file on expiry in which it is written that this PC, with xyz browser, entered the site this day.
We must imagine the cookie as if it were a certificate of participation that says "I have been here" or, in the case of sites like Google and Facebook, "I have been here and I have searched for this".
Cookies, in themselves, are not a problem at all, on the contrary, in some cases they are very useful to avoid, for example, the appearance of advertising popups more than once or to personalize searches or to receive automated suggestions that reflect their tastes.
Avoiding all this means maintaining your privacy, both towards other people who use the same computer, and to remain anonymous in the statistics of the various sites.
For example, you may want to prevent Google's search from being influenced by past searches, or you may prefer to enter Facebook without fear of leaving your login data in memory.
To protect your privacy on the internet, the most used web browsers such as Internet Explorer, Firefox, Chrome, Safari and Opera have implemented a function called "incognito" or "private" browsing .
Browsing the Internet incognito nothing is recorded on the history and the so-called cookies are not saved (in theory), so every time you go to a website, it will seem like it was the first time.
If in another article I said how to force browsers to open in private mode, on this occasion we see how we can use Google Chrome or Firefox to automatically set the visit to some chosen websites, with incognito mode, always .
You can then install an extension for Chrome called Incognito This to reopen an already open site, in private mode, with a click.
Once installed, you can go to the options menu of the extension and write the addresses of the websites on which you want to always and automatically browse incognito.
So, setting for example, www.navigaweb.net between the sites to be browsed in private, every time you happen on these pages, a new Google Chrome window will open without leaving any traces on that specific site or on your computer.
Also on Chrome a new extension that allows you to quickly add websites chosen for opening in incognito mode is Incognito-Filter
On Firefox, a similar extension is Open in Private Browsing Mode which allows you to choose some websites to automatically browse in private, without registering cookies.
It also adds an option if you right-click on a link to open that site in private mode.
