Can't log into amazon.co.uk account

[Cask]

Can anyone else log into their amazon.co.uk accounts? Firefox gives me:

Firefox and www.amazon.co.uk cannot communicate securely because they have no common encryption algorithms

using both the standard and secure servers apparently. And IE just gives me "This page cannot be displayed" screen. What's the deal.

Same error Cask, using Firefox 0.10.1 PR and IE 6 SP2 on Windows XP SP2 if that helps.
