Firefox stopped offering RC4 in initial handshake

Discussion created by David Henninger on Jan 19, 2015



While Firefox still has RC4 included and enabled, it stopped offering said cipher and only offers it when the initial connection fails.

Thus, servers no longer can push weak RC4 onto the client if there are better alternatives available.


Unfortunately, the browser check does not exclusively check for RC4, so Firefox is no longer listed as RC4-compatible.


Currently applies to Firefox Aurora (37+) and maybe Beta (36). Didn't test it yet.
