If you're trying to check on a FedEx shipment, you usually have to have a "user account" set up before you can get to information on a shipment. You can't (as an example) check on someone else's shipment unless they give you the tracking number/login (and one assumes, their permission to see it).

If you have the shipment tracking number, you might be able to get in; but they do have a reasonably (?????) secure system. Usually only the sender and/or recipient can get in with the shipment number, and if you've changed names, email addy, or address, since the shipment took place, they're unlikely to recognize you.

On sites where you have to login, individual pages may be secured so that you do have to open the page - and often you can't use a "save target" on a link from another page, even if the same login is good for both pages.

The blank page, error message and no header, usually means that a sign-in is required and you haven't done it.

I just hope they don't report you to the privacy police...
