How to enable, block and delete all cookies in Chrome, IE, Firefox, Opera and Safari. What are cookies and how to work with them? What are cookies

Almost every Windows user has encountered the concept of cookies. What they are, why they are needed and why it is advisable to clean them, read within the framework of this publication.

What are cookies

A cookie is a text file with data that is written to the browser by the server of the site you visit. These data are:

• login and password information;
• individual settings and user preferences;
• visit statistics, etc.

Using this data, the site you visited will be able to identify you. This happens as follows:

• the site server queries the browser for information in the cookie file;
• the browser provides this information by sending a response to the server;
• Depending on what information the site server receives, you will be identified or become a new person for the site (if the cookies are cleared).

The main parameter of a cookie is its expiration date. By default, this is one computer session. Files are deleted when the browser is closed. If they have an expiration date, they become permanent and are deleted upon expiration or by the browser cleanup function.

What are they needed for?

First of all, they are needed for the convenience of using the Internet. For example, once you log into your profile on the site, you will not need to constantly enter your login and password after closing the tab.

Also, thanks to cookies, individual account settings are saved. For example, some sites offer to add to favorites, change the design, change the interface using such files with an expiration date.

Where are cookies stored?

Files are saved in a custom folder. Each browser has its own path:

• Opera C:\Users\Username\AppData\Local\Opera Software\Opera
• Google Chrome C:\Users\Username\AppData\Local\Chromium
• Yandex.Browser C:\Users\User_Name\AppData\Local\Yandex\YandexBrowser
• Mozilla Firefox C:\Users\Username\AppData\Local\Mozilla\Firefox

Why clean?

It is advisable to clear your cookies from time to time. In addition to being useful, they can also cause some inconvenience:

1. They provide quick access to your profiles without entering a login and password. If a stranger is at your computer, he will be able to access your personal data.
2. In addition, if an unauthorized person ends up on your computer, you can track your browsing history using the uncleaned cookies. This is bad from a privacy perspective.
3. If the site processes your cookie incorrectly, you may not be able to log into your profile, or some functions on the web service will not work correctly.

How to clear cookies?

Here's an example of cleaning for popular browsers:

1. Opera. Ctrl+H → Clear history → Cookies and other data from sites.
2. Google Chrome. Ctrl+H → Clear history → Cookies, as well as other data from sites and plugins.
   
3. Yandex browser. Ctrl+H → Clear history → Cookies and other data from sites and modules.
4. Mozilla Firefox. Ctrl+Shift+Del → Cookies.

How to disable?

In general, the creation of cookies can be disabled in the browser. This feature is available in all popular browsers, so there shouldn't be any problems. But after turning off this function, some sites may stop working, since they interact with the user exclusively using cookies.

To disable in popular browsers:

Advice! If you see notifications in your browser: “cookies must be allowed” or “an attempt to save a cookie is blocked,” then your browser does not save cookies by default. Open settings and enable saving cookies.

Cookies store data from certain websites that is recorded by the browser. Every time you visit a site whose cookies have been stored in the browser’s memory, the browser sends a cookie back to the site. But when it closes, it accepts new ones.

Can cookies affect your browser?

With the help of cookies, sites whose data is recorded in these files will load faster, but the overall performance of the browser itself may decrease. This is especially true when the computer hardware is very weak and the amount of data in cookies is very large.

Based on this, it is recommended to clear cookies once every certain period of time, or even disable them in your browser. But if you choose the latter option, then a small percentage of sites that require these files may begin to function incorrectly.

Step 1: Disable cookies

At this stage, you will need these instructions:

1. Open "Settings" Yandex Browser. To do this, click on the three-bar element in the upper right part of the window. Then select the item from the context menu "Settings".




2. Scroll to the end of the page with basic settings and click on the inscription "Show advanced settings".




3. In the block "Personal data" click on the button "Content Settings".




4. A window will open where under the title "Cookies" you need to put a marker next to one of the points: "Don't allow sites to save data" or “Block data and cookies from third party sites”.




5. In the latter case, you can add some sites to exceptions. This way you can work with those resources that need to save cookies. However, other sites will not store their data without your permission. To add exceptions, use the button "Exception Management".




6. Here, using a special line, you can add a site or its page to the allowed list. To apply changes use the button "Ready".

Step 2: Removing remaining cookies

This procedure can be done in several ways, for example, using special cleaning programs or removing "Stories" in the browser. However, it is recommended to use one standard method if there are not many cookies stored in the browser:

If there are too many files and manually deleting each of them will take a long time, then use the following instructions:

As you can see, there is nothing complicated about disabling cookies in Yandex Browser. In addition, it is worth considering that the last step is optional, but it is recommended to do it if the browser begins to slow down due to accumulated cookie data.

The full functioning of websites is determined by many parameters. One of them is support for cookies, or the ability to use data generated by web pages that is stored in the computer's memory. In other words, cookies are text files containing information about the personal settings made on various types of Internet resources (design, time zone, city, etc.), as well as about the user’s activity and authentication (logging into an account ). They greatly simplify entering information when registering on websites or filling out other forms.

Among users of the World Wide Web, there is an opinion that activating cookies can harm the computer, like a virus, spyware or malware. This is wrong. By themselves, these files cannot perform any actions, being simple text data. They do not slow down the system and do not require systematic removal; they are stored in the PC memory until they expire.

Often, cookies are enabled by default in browsers. If they are disabled, then you need to know how to enable cookies yourself in a particular browser. Enabling cookie support is easy for both beginners and experienced users. Let's take a closer look at the features of their activation in the most popular browsers.
