hi, if you have parents who set those controls, then they'd have to lift the restrictions as well.

alternatively (and this is just a hunch, i don't know if it would work) you could try the steps mentioned in this ms help article for windows 8: https://support.microsoft.com/en-us/kb/2965142 - there's a section called Known issues for Firefox usersdescribing a workaround to import the necessary certificates into firefox...

hi muchispac, unfortunately this can currently happen on windows accounts that are restricted by the Microsoft Family safety settings - in order to disable those, please refer to http://windows.microsoft.com/en-us/windows-10/turn-off-microsoft-family-settings

This is what I did to fix the problem and it worked fine without having to disable Microsoft family safety.

To consent to such snooping, and suppress all "Untrusted Certificate" warnings arising from this scheme, you need to instruct Firefox to trust Microsoft's SSL certificate that is used for re-encrypting. (Microsoft Internet Explorer doesn't have this "problem" because it trusts Microsoft's certificate out of the box. Google Chrome is the same, since it relies on cryptography mechanisms built into Windows. Firefox, however, uses its own cryptographic routines that consult a separate list of trusted root certificates.)

The certificate that you need to import is Microsoft's. Go to Control Panel → Network and Internet → Internet Options → Content → Certificates → Trusted Root Certification Authorities. Select the Microsoft Family Safety certificate, then click Export…. Answer No, do not export the private key. Either of the two .CER formats is fine. Save it to any convenient temporary location, such as familysafety.cer on your Desktop.

Then, you need to tell Firefox to trust the certificate that you just exported. In the Firefox menu, choose Options → Advanced → Certificates → View Certificates → Authorities → Import…. Select the familysafety.cer that you had just saved. Select Trust this CA to identify websites, then click OK, and close the Options dialog.

Once you do this restart Firefox and you should have no problem
