Provides nothing over and above that shown in comment #2 from "journalctl -f"
and starting FF

I think the Gtk warnings about "No such file or directory" are rather a red
herring, as the referenced file is not present on my Leap 15.4 systems on which
FF 114 is working without this problem.

As I wrote in the initial post, FF is crashing before it even displays it's
GUI, it goes straight to the "Mozilla Crash Reporter" dialogue.

Starting FF from the command line with "firefox -safe-mode" also immediately
crashes.

The "real" information of use is probably the crash dump file produced which is
submitted to Mozilla via the "Mozilla Crash Reporter" - it's an approx 500k
binary file...
