Signon.oracle.com broken

I cannot make Kee extension in Firefox to fill in the login form on this page. https://signon.oracle.com/signin is the main Oracle login page, for example if you want to participate in discussion on VirtualBox forum.

I pasted URL from the address bar to the KeePass entry. On another attempt I created a new entry using Kee extension, it showed in KeePass, but it still doesn’t want to get filled.

Please help. Thanks.
