Error message when using FoxyProxy

Hi everyone! Hopefully someone more skilled than me can help with the error message I get saying: " Secure Connection Failed An error occurred during a connection to www.google.se. Peer’s certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Burp worked perfectly until yesterday. Any ideas?

Hi, Can you clarify both how you have obtained the Burp CA Certificate and how you have installed it? You mention this used to work perfectly, have you taken any actions since that point that might have changed how your setup works? Does this work if you remove FoxyProxy from the chain and just use the proxy settings within your browser?
