Comment 23 for bug 1849346

In my brand new Ubuntu 21.10 Impish has forced the change of Firefox as Snap, so I'm suffering Kerberos not working from inside the Firefox snap.
Kerberos works fine at Linux level.KInit, KList, etc... shows that the tickets are assigned and handle correctly when requested.

Which is different in our case that for normal people is that the use of Kerberos requires to set in firefox the preference "network.negotiate-auth.trusted-uris" which by default is not set.
In my case it is set as network.negotiate-auth.trusted-uris=cern.ch

I have everything setup correctly, linux and firefox snap, and the problem present so if somebody could guide me a bit I can output any log file/debug you wish to spot where the magic disappears.
