website compatibility

Possible bug?..If not what am I doing wrong?
Kee doesn’t fill in the log for
It doesn’t even initially place the icons in the username and password boxes.
For some reason, opening another tab, gets it to fill in the log in information, and display the icons in the boxes.
I’m running the latest Firefox Quantum 59.0.1 64 bit version on a Windows machine.
My Kee works on other sites to log me in, and the old version KeeFox, worked to log into this site, perfectly.
KeePass version 2.38
Favicon Downloader 1.9
KeePassRPC 1.7.3

Thank you in advance, for whatever help comes from this!
