I am having a lot of trouble with security certificates for different sites. Messages keep coming up about invalid security certificates and it isn't true. I have to check my PayPal account and I can't get into it. eBay also register as invalid security certificates.

Make sure that your security software isn't intercepting secure connections and send its own certificate.

You can retrieve the certificate and check who issued the certificate.

  • 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 to inspect the certificate and check who is the issuer and other details.
