Sorry, I can't deal with the randomness. Let's simplify -

$ sudo snap disable firefox
firefox disabled

$ cat ~/.local/share/applications/firefox2.desktop
[Desktop Entry]
Version=1.0
Name=Firefox Web Browser 2
Exec=/bin/bash -c "/home/alan/firefox-104.0.2/firefox/firefox"
Terminal=false
X-MultipleArgs=false
Type=Application
Icon=firefox
Categories=GNOME;GTK;Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;video/webm;application/x-xpinstall;
StartupNotify=true
StartupWMClass=firefox
$

With the above, if I log in and click firefox, I get stuck at the black window. If I quit firefox and try again, I get a *temporary* black window, and then a working firefox.

If I edit the file and change it to "MOZ_ENABLE_WAYLAND=1 /home/alan/firefox-104.0.2/firefox/firefox", then two things change:

1. When I log in and click firefox, firefox works the first time. I don't have to quit it and click it again before I can use firefox.
2. When firefox starts, there is no *temporary* black screen either.

When I *was* trying to launch firefox from the terminal, I also noticed a difference in debug messages:
