Can someone explain what is a proxy setting and how it works? or What is a proxy setting and why woul

Proxy settings act like a middleman between you and the internet. They can mask your IP, but they don’t encrypt your traffic like a VPN does.

For setup, it depends on your OS. On Chrome, you can tweak it under Settings > Advanced > System. Or use a tool like CCProxy if you want more control.

Just FYI, free proxies can be slow or even unsafe. Proceed with caution!
