I can't answer as to Firefox flatpaks, but I can with another package, MuseScore. On my PC, a RPM version of MuseScore works as expected, the flatpak version cannot print. You can go through the motions, select your printer as expected, but nothing ever comes out of the printer. I see that problem has existed for well over a year without a fix.
Flatpaks are an attempt to make an all-purpose single package that will work on all distros. Sometimes they (flatpak creators) don't get it right and your distro is too different from theirs, and things mayn't work. I can forsee that if things continue to go down that route they'll start advising people who can't get a package to work to change distros, instead of fixing their flatpak.
A correction to my previous post, it was an appimage, not a flatpak, that I had problems with. Though the reasoning is the same (flatpaks and appimages have similar goals and potential problems).
