You should surf internet anonymously so you will be safe & secure and it ensure that your privacy is protected. No one is able to track you and you should not post your personal information on Internet because internet is a public place. There are many advantages of staying anonymous. For staying anonymous you need to use a VPN (Virtual Private Network) which hides you and I would suggest you to use Tor Browser instead of Chrome Browser because tor browser hides your identity over internet by using proxies. If you want to use a paid VPN you can use Nord VPN otherwise if you want to use a free one you should use Proton VPN because it is best free VPN.
