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: $ /bin/bash -c "/home/alan/firefox-104.0.2/firefox/firefox" ATTENTION: default value of option mesa_glthread overridden by environment.
