You have probably seen that in many sites, when you enter them, there is a request to " store a cookie in your browser", so it is important to start by letting you know that Cookies are nothing more than files that websites collect with activity data. of the user: from where it connects, at what time, what device it has, and so on. The idea is, once more, to offer the most personalized navigation possible.
However, users may be reluctant to store any type of information about them. It is true that some of them, called "zombie cookies", can be a threat to privacy, precisely because they are stored on the device and not in the browser, and are regenerated even if they are deleted.
Normally, however, cookies are nothing more than a small file that makes our way through a web page somewhat faster and more accessible.
It does not hurt to learn to control under what terms and conditions our data are kept, as well as for what purpose. Some web pages include a detailed breakdown of the cookies they collect (their duration, purpose, browser ...) but most do not, so the user has no way of knowing where to remove them.
But we can always resort to some extensions that fulfill this service. For Google Chrome, for example, the user can access Vanilla Cookie Manager or Edit This Cookie . Both are free and their performance is similar: they generate a list with all the web pages to which we have allowed, at some time, generate cookies from our navigation. They can be deleted, edited or blocked from the browser itself. For Firefox we find new extensions, such as Cookies Manager +.
As for Safari , the thing changes a bit: the browser allows you to manage cookies directly from the Preferences panel, so that the user decides whether to accept them all, blocks them, or can continue to ask the user.
Going into Privacy and then into "website management", a list will be generated - far longer than the user might think - with all the sites that store information. Eliminating or not will be your own decision, but it is important to know where our behavior on the Internet is studied.
