Cookies, also called HTTP cookies or browser cookies, are small, often encrypted files that are stored on your computer whenever a website user visits a website. Cookies are used by website owners to perform tasks and help with managing the website. With the help of cookies, the website remembers the user's preferences and other changes, made during the last visit. There are different types of cookies.
Cookies could be enabled or disabled by changing website browser settings. Depending on the device, operating system, and the internet browser, there are different ways how to disable cookies. Please read this article to know in what cases you should disable cookies and the guides on how to disable them.
Should I Disable Cookies?
Pros of disabling cookies
Disabling cookies could give you more privacy on the internet. This could be especially helpful if you share your device with another person. If you use a public computer to check an email or to shop online, the next person who uses that computer could potentially see your entire internet activity. Or worse still, the next person could log in to your online banking or shopping accounts instead of you.
Cookies could pose a security threat. There were cyberattacks in the past, which have demonstrated that hackers can potentially hijack cookies, gain access to browser sessions, and then steal personal data.
Cookies can slow your browser down. When you first visit a website, the pages you visit will get saved onto your hard drive with the help of cookies. On subsequent visits, these pages will load faster. However, over time you may accumulate many cookies and this will slow your device down.
By disabling cookies you will see fewer targeted ads. Without cookies, website owners, especially third-parties, won’t be able to track your activity and count how many times you visit their sites or which sites or products you prefer. When cookies are disabled, your personal information is not shared with any companies.
Cons of disabling cookies
Many websites rely heavily on cookies. Some cookies are vital for a website to function properly. For example, if you are using an online shop and you want to put an item into your shopping bag, you will need to accept cookies to perform such an action. Disabling all cookies will log you out of all your accounts and could prevent you from using online services, such as online shopping.
Cookies can give you convenience. Cookies track website users’ activity when they surf the internet. For example, when the user logs into an account like Gmail or Facebook for the first time, he has to enter his username and password. When he visits these websites again, with the help of cookies the websites remember and show his profile username. The user just needs to enter his password. Websites also track users' location and provide the most relevant information in the users' area based on their location.
Cookies also allow compliance with the privacy laws. Through a function of geo-targeting websites get the website user's location and provide him the most relevant Cookie Banner based on his location and legal requirements of that country. The banner appears in the user language and is adapted to the relevant privacy laws, so if you disable cookies, you could not be sure that your personal data are treated according to the laws.
Even if it is not recommended to disable all cookies to allow the websites to work properly, it could be a good practice to periodically delete cookies, which are already saved to your computer. The reasons for deleting cookies are the same as for disabling them.
- Cookies could pose a security threat.
- Cookies can slow your browser down.
- Cookies allow targeted ads.
- You should delete cookies after you use a public or shared computer.
Deleting cookies could be a preferred option over disabling them since during the internet session you could use all the functionality of the websites, and eliminate the potential risks of using cookies after you finished your session.
You could delete existing cookies at any time, even if you initially enabled them. However, deleting cookies makes online browsing less convenient. After you clear your saved cookies, your browser won’t remember your favorite websites or log in details. Without cookies, you’ll be logged out of all your online accounts and you could not add any items to your virtual shopping cart.
In addition, the ads and video or music suggestions you see online will be irrelevant to you.
Please note that deleting cookies doesn’t eliminate all data tracking. Many websites can reconstruct your identity, unless you clear your cache and browsing history, too. Even then your device can still be fingerprinted. Website owners can identify you by gathering information on your device’s browser type, operating system, screen resolution, unique plugins, and other data.
Options for Enabling or Disabling Cookies
Each website user could choose between the convenient internet experience and the security risks based on his preferences. The user usually has three general options regarding cookie permission:
- Enable all cookies
- Disable all cookies
- Enable just first-party cookies, and disable Third-Party Cookies.
Enable all cookies. If the website user wants to have the most convenient and personalized internet experience, he should allow both first-party and Third-Party Cookies to be used on websites he visits. Websites will remember important information and user preferences, such as login data, region, language, and enhanced content. It saves time for website users, allows them to get personalized content and ads, and increases the functionality of websites. This option is recommended for the users who want to get the best internet browsing experience and the most functionality of the websites while sharing their data with website owners and third-parties.
Disable all cookies. Disabling cookies entirely is not recommended since many websites will not function normally. Disabling first-party and Third-Party Cookies will log you out of all your accounts and could prevent you from using online services, such as online shopping. You will also have to log in with full credentials every time you visit a website. If you disable all cookies, websites could not offer you personalized content, such as offering you videos or music based on your preferences and internet browsing history. If you don’t mind logging in every time you want to access a particular service, and you don't want the websites to remember your preferences, then you can disable cookies. Just be aware that you may have to turn on cookies for certain websites to access full services.
If you choose to disable all cookies, you could also block fingerprints. Fingerprinting takes place when a website owner creates a profile of your device's unique characteristics, such as the hardware, software, and add-ons you use.
Enable just first-party cookies, and disable Third-Party Cookies. The balanced option for choosing between a convenient internet browsing experience and your personal data security could be achieved by enabling first-party cookies and disabling Third-Party Cookies. In this case, the website user could use all the functions of the website normally but his personal data will not be accessed by third-parties.
If you block third-party cookies, it does not mean that you will not see advertisements on the websites. You will simply see not personalized advertisements. However, in a few years, the use of Third-Party Cookies could be limited. Google has announced that by the end of 2023 it will officially have new strategies to be able to advertise without relying solely on third-party cookies.
Some browsers, for example, Firefox, offer advanced browser privacy settings when control of the privacy and cookies settings are combined together. The user can choose one of the three main options for privacy and cookies management: Standard, Strict, and Custom. The standard option allows most of the first-party cookies that most websites need to work properly and blocks Third-Party Cookies that are often used by companies to track user behavior across multiple websites. The Strict option still allows essential first-party cookies which most websites need and blocks third-party Tracking Cookies, cryptocurrency miners, social media trackers, and fingerprinters. The Custom option gives you the biggest control over what will be allowed or blocked by Firefox.
Some browsers have an option “Do not track”, which could be turned on or off at the browser settings. By this function, you inform the website how to treat your personal data. It is turned off by default. However, it depends on a website, if this option is executed and how the website responds to the request. Many websites will still collect and use your browsing data to improve services and security, as well as collect your behavior statistics to provide you personalized ads and recommendations. Most websites, including Google's, don't change their behavior when they receive a Do not track request. Website browsers do not provide details on how websites interpret the request.
