Public bug reported: I use the mozilla-team-ppa for Firefox and was not able to open downloaded files directly from Firefox itself. It only gave me a file picker to open file-links.
After open Firefox from the shell I saw this message: ** (firefox:1628082): WARNING **: 14:27:58.603: Cannot launch default application: Kindprozess »/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop« konnte nicht ausgeführt werden (Keine Berechtigung) [Parent 1628082, Main Thread] WARNING: Cannot launch application: Kindprozess »/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop« konnte nicht ausgeführt werden (Keine Berechtigung): 'glib warning', file /build/firefox-J0YjYH/firefox-130.0+build2/toolkit/xre/nsSigHandlers.cpp:187 Which I fixed after adding to following content to the /etc/apparmor.d/usr.bin.firefox # Allow opening links /usr/lib/@{multiarch}/glib-[0-9]*/gio-launch-desktop ix, and forced a reload with sudo apparmor_parser -r /etc/apparmor.d/usr.bin.firefox Please include this to the Firefox packages.
