I am routing a Linux machine through a SOCKS5 proxy. The internet works as expected and I am presented with the proxy's IP when viewing http://whatismyip.com.
However, some sites are reporting that I am experiencing a MITM attack:
Software is Preventing Firefox From Safely Connecting to This Site
www.mozilla.org is most likely a safe site, but a secure connection could not be established. This issue is caused by DigiCert Global Root CA, which is either software on your computer or your network.
What can you do about it?
www.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
If your antivirus software includes a feature that scans encrypted connections (often called “web scanning” or “https scanning”), you can disable that feature. If that doesn’t work, you can remove and reinstall the antivirus software.
If you are on a corporate network, you can contact your IT department.
If you are not familiar with DigiCert Global Root CA, then this could be an attack, and there is nothing you can do to access the site.

Your connection is being intercepted by a TLS proxy. Uninstall it if possible or configure your device to trust its root certificate.
HTTP Strict Transport Security: true
HTTP Public Key Pinning: false

How do I alleviate this error so that I can access these sites? Do I need to accept some certificate on my local machine or on the proxy?
