MOZILLA_PKIX_ERROR_MITM_DETECTED?

Question

I've just installed ubuntu 16.04 onto my laptop, but every time I try using a site on my Firefox browser I get a 'mozilla_pkix_error_mitm_detected' error? Reading the details of the error message, it says that a connection couldn't be established because of my default route. I know little about networking, so I'm clueless as to what to do here. Someone help please?

You could enter about:config into the firefox address bar (confirm the info message in case it shows up) and search for the preference named security.enterprise_roots.enabled double-click it and change its value to true and restart firefox.
