Cookies are small files in which the browser can record data from sites you visit. Normally, websites store cookies in the user's browser in order to "recognize" the visitor (for example, to avoid asking for the username and password of a user who recently logged in on this website).
There are certain privacy risks associated with using cookies. For example, if masked passwords are stored in cookies, someone else with access to your computer could get into your accounts for internet applications. Cookies can be used for finding out which websites you visited or identifying the relationship between browsing different sites. For this reason, the browser allows you to control cookie handling in Settings.
In the lower part of the Settings page, click the Show advanced settings button.
In the Privacy section, click Content settings.
Regularly deletingcookie files reduces the risk of a malicious user obtaining information on your internet activities. In addition, deleting cookies can free up hard disk space (the browser allocates part of the memory for cookies and if you visit lots of different websites this can be quite large).
To clear cookies:
You can remove cookies that were previously installed by a specific page, or forbid this page to save cookies on your computer.
You can set exceptions for cookies in the browser settings.
