Hello, I have had the same problem. The problem is not only with firefox, it is also valid with thunderbird in my experience.
I have debugged a bit using truss(1) and identified that the ~/.Xauthority file and /etc/hosts is the problem. Actually, the problem is firefox and thunderbird, but the initiators are them. Check what display-names are displayed with `xauth list`. If you see a display name as an invalid host in /etc/hosts, simply remove it with `xauth remove`. My problem is that I changed the hostname, and it stayed after a firefox upgrade, so I had two entries with an invalid hostname and a valid hostname in .Xauthority. See also /etc/hosts to see if there is an invalid host or check if you do not have any entries where a host (such as your hostname) is missing. El 17 de agosto de 2022 4:55:20 p. m.
