Cookies are nothing more than small files that are stored within the web browser and are created by the websites that we visit automatically. These are responsible for sending a small amount of data between the sender and the receiver and that used for bad purposes can be dangerous.
Back in 2012 a European regulation on cookies was approved. It specifies that the websites must inform us about the installation of cookies by asking us for our consent beforehand, something that is not being fulfilled as it should. This is compounded knowing that a good number of websites have third-party cookie services to collect our browsing history to create advertising profiles.
In addition, we can meet security issues when we connect to unsecured networks such as public WiFi. From here, a hacker could use the cookies that identify us when accessing one of our social networks, being able to resend that same cookie to impersonate our identity on that same website.
But not only cookies are a problem for our privacy and security on the Internet, but they can also end up overloading our browser, which makes it consume more resources and your performance decreases, becoming slower.
When we talk about the term deleting cookies, we mean deleting a lot of information stored in our browser, such as data from websites and passwords. Therefore, in case of deleting all this data, we will have to fill it in again when we access that website again.
To delete cookies, we will only have to access the configuration section of our browser. From there we erase all browsing history including cookies. This is something that is very easy to do, especially if we use some of the most popular web browsers such as Chrome, Edge, Firefox, etc.
If we do not want to delete cookies, we can also prevent tracking using the incognito mode of our browser. In this case, although web cookies are inserted in the browser, but without saving the URL from which it was accessed.
