I've tried opening the "Add Security Exception" tab and getting a certificate, but it says it can't get the certificate.

Firefox is denying me access to Facebook, as well as my Amazon account, as it says it can't trust the certificate. I've tried doing what the forum says, going to "Add Security Exception", and pasting the FB address in, but it just says it can't get the certificate. This has only happened recently, since I upgraded to Windows 10. Could that have anything to do with it?

It's supremely frustrating and, having used Firefox for many years, I'm ready to go to Chrome or even....Microsoft's new browser.

Thanks - that's worked. What a relief!
