Shopping basket greyed out

I have items in the basket but cannot view them or pay for them. I can add additional items though!! Mac OS 10.13 latest Firefox 115.17.0

If I am not mistaken, Apple stopped supporting OS 10.13 in 2020.

Can you check out using your phone or another device?

Yes, phone or Chrome. You are correct, there is no longer support for the OS but it is the last OS my iMac can run.
