[Grml] security protocol iceweasel question

Dear M and friends,

I know I must have done something wrong, but

http://www.nais.org/LoginPre.cfm then, trying to go to sssonline gives me the error that iceweasel cannot connect because of a security protocol that is not enabled.

It worked in grml 0.8, so I have somehow disabled something it needs, as the same type of error occurs in opera, galeon, et al.

Help, please, as there must be something I did in runlevel.conf, or somewhere.

Most other secure sites work.

This is rather urgent, actually.

Best, M
