Website will not load at all in Firefox
We have an intranet site that works fine in Chrome and Edge, but does not load at all in Firefox. In Firefox, an authentication dialog appears, but after entering correct credentials, it just re-shows the same authentication dialog after a few seconds. This repeats indefinitely. There is no useful info (and pretty much no info of any kind) in the dev tools. I have tried Firefox in safe mode, with no changes to the behavior.
What steps can I try to debug this problem?

In case it matters, the server is running IIS on Windows Server 2012 R2, and the website is built on the Expression Engine CMS.
Try to enter about:config in the address bar and set network.automatic-ntlm-auth.trusted-uris = yourdomain, where yourdomain is your domain, then restart.
I have added mydomain to network.automatic-ntlm-auth.trusted-uris and it have worked previously.
But now on firefox 111 and later it doesn't work and no login-window is shown.
The server is responding with this headers, so some auth is required but firefox doesn't even try.

You can automate the process with a program called mozregression.
