In the old extensions page a guest can navigate there, they just don't see the extensions. Should we do the same?

I'd rather show *something* that show a 404 page or similar. Even a page that just says that "Extension management is not available to Guest users. Please sign in to manage extensions".

Attached are screenshots of what we do in the old extensions and md-extensions page for Guest mode. It’s essentially the same.

As dschuyler@ suggests, we could add a string that says "Extension management is not available to Guest users. Please sign in to manage extensions". Maybe we should even remove the link to the Chrome Web Store because CWS will not permit extension downloading anyway.
