[V13P] SSL pain relief

Summary: PortSwigger fixed a Burp Suite issue where Firefox, after changing how it handles root CA certificates in v3.5, stopped accepting Burp's generated root CA certificate, which Burp introduced in v1.2.11 to sign per-host certificates and eliminate SSL errors. Burp also added a setting to specify which protocols are offered to servers during SSL negotiation, to work around failures in the Java SSL stack with certain unusual server configurations.

Key Takeaway: Users who previously installed Burp's CA certificate in a browser may need to remove it before installing the new root certificate, and PortSwigger notes the protocol setting should not be used to test which protocols a server actually supports.
