Summary: Google researchers have discovered a plaintext recovery attack
against SSL 3.0 with no known mitigation.

I would like us to ship Firefox with SSL 3.0 disabled by default.  This
means setting security.tls.version.min to 1, or, in terms of code,
changing the initial value of PSM_DEFAULT_MIN_TLS_VERSION from 0 to 1 in
security/manager/ssl/src/nsNSSComponent.cpp.  I assume that other
Mozilla ports use the same code and require the same changes.

Note that this does not preclude the user from changing the setting back
to 0 in about:config.

I would also like to do the same for Chrome, but I don't know the exact
procedure and I am unable to find out or test, since Chrome has been
broken for several months.
