Proxy with login and password authorization

If an HTTP proxy with authorization is used, then a window with a login and password will appear as soon as you open any site on the Internet.

Browsers do not support Socks proxies with authorization. In such cases, it is necessary to use proxy programs. For example, Proxifier.
