I'm trying to make sure SSL 3.0 and TSL 1.0 are both enabled on the newest verison of Firefox. I believe TSL is enabled by default. But what about SSL 3.0?

hi ant0208, ssl 3.0 is a broken and therefore insecure protocol and modern browsers may no longer support it: https://tools.ietf.org/html/rfc7568
