I'm seeing the same thing you are describing. As long as you have that panel at the left side of the screen you can click on the Amazon logo just under the little search box and you will be taken to the Amazon.com location proper and everything should be fine from that point.
Whatever is going on with the 3FC page, I'm sure Suzanne will take a look at it as soon as she gets a change. BUT, if the link at the left still works you will still be supporting 3FC as you shop.
PS . . . I am using IE so I can't tell you about Firefox or Chrome.
