Cookies are text files that contain packets of information about the websites you have visited, and they help websites recognize your computer so that you can serve up content faster.
Cookies also store details such as your username and password, this way you don't have to re-enter your credentials every time you log into a website.
Origin of cookies
Cookies were invented in 1994 to ease the overload of e-commerce stores that were rampant on the Internet at the time.
Nowadays details such as your shopping cart information are stored in your web browser rather than the store database, so when you navigate away from the page the items you previously added to your cart will remain.
Common types of cookies
Cookies are generally safe to use and do not contain any malware.
Here are some common examples you will encounter:
Session cookies:
These are temporary files that are deleted once your session ends or when you close your browser. They help you navigate the site without tracking your browsing habits.
Persistent cookies:
This type of cookie is used for website authentication. It is also used by many online merchants in their remarketing practices, where they serve you targeted advertisements or suggest items in their stores. Persistent cookies are also stored on your computer your account until it expires or you delete it.
Secure cookies: Secure cookies
cannot be used by malware, as they are usually written in scripting languages such as JavaScript.
Third-Party Cookies:
Pages containing advertisements may create cookies that grant access to third parties, so even if you don't click on any of the ads, advertisers can use them to track your browsing history.
It should be noted here that the latter type causes concern, as it tracks and stores data without your explicit permission or knowledge.

Why do companies use cookies?
The main reasons for using cookies include:
Improve the
on-site experience by getting to know users and remembering their login information and preferences.
Personalize and target ads
based on browsing history, and boost sales by tracking previously viewed items, shopping preferences, engagement and behavior on the site.
The dangers of cookies
Some cookies may be necessary for the basic functionality of a website, but most cookies are used for statistical and marketing purposes and for collecting personal data such as user behavior and search history.
This data is often shared with third parties such as technology companies, social networks, media platforms, and data brokers.
So while cookies help your website to function and give you insight into its performance and conversions, they also pose some risk to your business.
As an Internet user, it is wise to understand the risks of cookies so that you can view and delete them when necessary. Here are the most prominent ones:
Privacy violation:
For most internet users privacy is their primary concern, when it comes to online cookies important search engines and other advertising systems track users and use the information to serve ads, of course many users feel this is a blatant privacy violation.
Cookie fraud using fraudulent cookies:
Cookies are used to either defraud legitimate users or to use the identity of legitimate users to perform malicious acts.
To avoid fraud it is important to keep your browser up to date as many cookie scams are designed to take advantage of security holes in older browsers.
It is also important to avoid questionable sites and to be alert if your browser warns you that a site may be malicious.

How can cookies be turned off?
What pop-ups usually do is tell you that the page you're visiting is using cookies to give you a better experience.
But, at this point you may have stopped reading and pressed the accept button, and so did exactly what the website wanted you to do, i.e. agreed to be tracked.
However, there are ways to refuse cookies and prevent those pop-ups from appearing at all.
A new one has been announced called Never-Consent from Ghostery which specializes in privacy-focused web tools.
Never-Consent blocks pop-ups and rejects cookies automatically, all you have to do is install the extension and it will do the work for you.
It should be noted here that browser extensions and the companies that manufacture them can also track you, so be careful who you trust.
If you don't want to bother searching for and installing browser extensions, there are a few other methods you can try to do something similar to Never-Consent, where you can use a browser that blocks cookies by default, almost all browsers do this except Chrome ( Chrome) which is the most popular.
There is also a Global Privacy Control service that automatically tells websites not to sell or share user data, but this is not available in all browsers, especially chrome and safari.
The Ghostery extension blocks third-party cookies but now you'll also be able to tell websites that you don't want to be tracked as well as passively block their cookies.
Don't think that the days of annoying or tracking popups are gone forever, as companies are using them more and more to encourage you to sign up for newsletters and marketing emails for advertising and marketing purposes.
This is their way of collecting data about you, and now that cookies are on the way out as we've seen, companies are always looking for effective alternatives to carry out their agendas in their own interest, and will likely devise a new way to track you and make money from you if their current method is blocked.
