When your browser throws a certificate warning, it's basically saying, 'Hey, I can't fully trust this website's identity.' This usually happens because the site's SSL certificate is expired, misconfigured, or doesn't match the domain you're trying to visit. You can check the certificate details by clicking on the padlock icon in the address bar, then selecting 'Certificate' to see its issuer and validity dates.
