Neither Google Chrome nor Firefox trust the presented TLS certificate's authority (IPFire CA), resulting in a certificate error. As the website is for security based software, it is of the utmost importance that a valid, verifiable certificate is used, and the website auto-redirects to the https connection. Strong, valid certificates are instantly and freely available from Lets Encrypt: https://letsencrypt.org/ If you could resolve this ASAP I would be very grateful.
Why has nothing been done about this?

Thank you!
