All https sites blocked with unknown issuer error message
Every time I try to access an https site Firefox blocks it. From what I have read this could be antivirus intercepting it, so I have deleted all antivirus apart from the Windows defender already on my system, but I still have the problem. Any suggestions much appreciated!
This is the error message I get:
https://support.mozilla.org/1/firefox/60.0.1/WINNT/en-GB/security-error
