My job requires login to most internal websites via Microsoft Azure AD SSO using Kerberos authentication using passwordless, smart card auth.
This switch happened this week. Up until yesterday I was 100% Firefox until this.
Firefox for MacOS is not able to do this. I spent an hour or so looking for solutions. Chrome on MacOS also doesn't. Safari does and now I have to fucking use Safari FFS.
I did. Unfortunately for the Mac it's a no-go. It was a good 10 year run :(
