Cookies are pieces of data that are saved in your web browser by the websites you visit. Third-party cookies are created by a website other than the one that you wanted to visit. Most of the time, third-party cookies are used by ad services that want to offer you targeted ads based on your browsing history and your web searches. However, these cookies can raise privacy concerns, as they can also be used to store your browsing history across websites that use the same ad services. That’s why questions like “Are third party cookies a security risk?” or “Is it good to block third party cookies?” often arise.
