running the how's my ssl check the tor browser rated bad, the reason the tor browser is using old tls settings and old security cipers,

In the next update please set the minimum tls to 2 and the maximum to 3 in about:config for security.tls.version this makes the minimum tls 1.1 and my max tls 1.2.

Also please disable use of insecure cipher suites security.ssl3.rsa_fips_des_ede3_sha in about:config

Just stumbled across this issue myself, good to see it logged. The latest Firefox (29.0.1) provides an almost identical fix as listed above, with the only difference being that it leaves the minimum TLS version at 0

Is there a way that I can contribute to fixing this? Submit a diff? (How?) Log in somewhere and change a config then submit for approval? Something else?

Happy to contribute where I can.

We have everything this bug complains about apart from the tls min version. However, a fix for that landed recently:, so it seems Mozilla is confident this sticks and is not impacting usability too much. We could probably think about backporting that fix into our alpha series. Dunno what the real browser devs think about that, though. :)

Either way, this will be fixed in esr78.
