I suspect that this question might be off topic here as it's not really about Tor. I'm unsure if there's a better SE to ask Firefox related questions on.
Anyone have thoughts? Please vote to close if you think it's off topic.
I actually up-voted the question since it asks about how to improve SSL/TLS connections within Tor Browser without affecting anonymity. The idea that a different TLS setting and different cipher list could be used to fingerprint a user is certainly on-topic, so asking how to improve that within Tor Browser without making your fingerprint stand out would seem a valid question to me.
