How to clear cookies in several popular browsers

A person who is only familiar with using the resources of the global Internet network, at first glance, it may seem that, apart from annoying advertisements on the sites, there are no special features: the selected program for viewing pages (the browser) sends requests, and distant servers return a response.

In fact, everything is a bit more complicated and there are some features that significantly expand the "request-response" scheme. One of them is cookies. They are small files with a size of 4 kilobytes, containing certain textual information. Often, users do not even suspect that their browser is actively using cookies. When a user's Internet client accesses the server, the latter sends a special file to the server - cookies. It contains information that allows you to identify the user. In the future, each new connection to this resource begins when the browser sends a file to the server. As a result, the user enters the site already under their login / password, and the page is displayed exactly as it was configured at the previous visit. Here is an example with the site of TV-programs: the visitor registers and selects the list of displayed channels. If the server assumes the use of cookies, then when you visit this site, only the selected channels will be displayed next time. In fact, the possibilities are much broader, but their review goes beyond the scope of the article.

Since these small files contain information that allows to identify the visitor, it is quite understandable why the question "How to clear cookies?" Is often asked. If the computer is in one-to-one use, then you can not think about such security. But if you can access the system of third parties, they have the opportunity to access sites using data stored in cookies. A user who does not know how to clear cookies or who did not perform this operation in a timely manner is at risk of making purchases from his accounts and some other troubles, such as viewing all the pages he visited. Obviously, you should not forget about security.

Before you learn how to clear cookies, it should be noted that these small files are still needed, since they greatly simplify the work on the Web. Therefore, it is recommended that you save the cookie file on a separate medium or archive it with a password. Sometimes such an archive is simply irreplaceable.

The answer to the question "How to delete cookies?" Depends on the browser you are using. In each of them, you can select several modes of operation: delete cookies when you exit the browser, do not accept at all, display a query.

If the user uses Opera, but does not know how to clear the cookies, you should proceed as follows: click in the browser Ctrl + F12, proceed to the "Advanced" and select "Cookies". By pressing the control button, you can erase unwanted entries.

In Firefox it's still easier: Settings - Privacy. In the menu "Delete individual cookies" it is possible to erase them selectively or immediately all.

In the Windows Internet Explorer, you need to select "General" in the properties, where in the browsing history, delete the temporary Internet files .

In Google Chrome, you need to open the settings, select the advanced view and, by checking the boxes, selectively clear the history.

There is a more convenient way to clean cookies. It consists in the use of special programs. One of the most popular is CCleaner. In it you need to click "Clean up" and select cookies. The program has great capabilities, so remove the check marks from those operations that you do not need to perform. In the settings, you can specify which cookies you want to save. It is not recommended to ignore the creation of a backup reg-file: its size is small, but with possible problems it is easy to restore the previous state of the system registry.
