Hey. Im having a problem on ALL https-starting sites. When i try to in example connect https://addons.mozilla.org/ , i get just this: http://i.imgur.com/2zPE8.jpg

I have already tried to reboot computer, boot FF without addons, reinstall firefox etc, but the problem still stays. With IE everything seems to work fine, but i would still like to use firefox.

Which security software (firewall, anti-virus) do you have?

Some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.
If you have ESET then see:

  • ESET setup -> advanced setup -> extend web and email tree -> SSL
  • SSL protocol: Do not scan SSL protocol

You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.

  • Click the link at the bottom of the error page: "I Understand the Risks"

Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".

  • Click the "View..." button and inspect the certificate and check who is the issuer.

You can see more Details like intermediate certificates that are used in the Details pane.
