Beveiligde verbinding mislukt / Secure connection failed
[NL] Als ik sites als facebook.com en youtube.com wil openen krijg ik de melding "Beveiligde verbinding mislukt". Hoe los ik dit op? Andere sites als google.com, 9gag.com en instagram.com (eigenlijk alle andere sites die ik uitgeprobeerd heb) doen het wel!

What Anti-Virus security software do you have?
There is security software like Avast and Kaspersky that intercept secure connections and send their own certificate.
If you can't inspect the certificate via "I Understand the Risks" then try this:
Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:
- chrome://pippki/content/exceptionDialog.xul
In the location field of this window type or paste the URL of the website.
- retrieve the certificate via the "Get certificate" button
- click the "View..." button to inspect the certificate in the Certificate Viewer
You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then you can attach a screenshot that shows the certificate viewer.

This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.

@cor-el I was thinking the same because I had Avast indeed. But I changed to Avira and the problem is still there :(
Now I'm gonna try that link you sent, I will let you know if it worked or not!

It is not working again... the notification says the following: "This website uses HTTP Strict Transport Security (HSTS) to indicate that Firefox only is allowed to make a secured connection. Because of this, it is not possible to add an exception for this certificate."
I think this is the problem ... How do I fix it?
It is solved! Thanks everybody for helping!!
You're welcome.
To elaborate:
This is with Microsoft Family Safety as you can see in the screenshot.
