SSL behavior on Windows XP with Firefox - beast mitigation with AES128 ?

One environment the ssllabs test unfortunately does not show is Windows XP with Firefox.


I've noticed if I work out a cipher list that achieves Beast mitigation, it will typically cause Firefox on XP to go into RC4


Is it possible to get Firefox on XP to use AES128 (for server-side performance w/AESNI acceleration) over RC4 while still blocking beast?


I've attempted this for several hours of tinkering now, so I give up.


Would love to hear if it's theoretically possible and what to try.


Server side is nginx with openssl 1.0.1e with EC enabled for FS


Thanks for any suggestions.
