I am unable to login to Apple Maps Connect

Hoping someone can assist with me.

I have been trying to login to Apple Maps Connect to list my business as a supplier, using my valid Apple id and username.

First roadblock I encounter:

https://mapsconnect.apple.com/unsupported_browser

The browser I have Safari v5.1.10.

So next, I try again with latest version of Firefox

https://mapsconnect.apple.com/

I attempt to login with my valid Apple id and username and link to a page with:

"No CSRF token found in headers"
