Hello. Recently I updated to Windows 10, and since then, Avast has given me problems with searching on Firefox. Whenever the shields are on, I get this message:

"An error occurred during a connection to www.facebook.com. Peer's certificate has an invalid signature. (Error code: sec_error_bad_signature) "

Any ideas for a fix?
