My understanding is yes it is, but there is nothing said clients can do on their end about it.

Depends on what you mean by "at risk", but somewhat, yes.

The attacker basically records a large number of your TLS handshakes from the wire, and then gets the SSL2 server to decrypt them. Because SSL2 is just that broken. There's really nothing you can do about the general attack on the client end.

On the other hand, the more efficient attack, using JavaScript to make your browser quickly send off the necessary 1000-ish TLS handshakes - that can be killed off by NoScript.
