Please, seek for various messages reported during this action:
- Emacs *Messages* buffer (C-h C-e)
- Firefox console (Ctrl+Shift+J)
- stderr of the Firefox process, unsure where it can be expected for 
flatpak apps: terminal application from which Firefox was initially 
started, output of "journalctl --user", in earlier days X11 errors may 
be saved to ~/.xsession-errors
- flatpak may have its own log file.

It is rather strange that Firefox receives some event, xdg-open works in 
isolation, but not from Emacs. What does happen when
- `browse-url' is called from Emacs,
- a link is activated in an Org document when Firefox application is closed?

Notice that you did not specify which versions of Emacs and Org you have 
installed (M-x org-version), and the source of the package: bundled with 
emacs, elpa-org deb package, Emacs ELPA package, etc.
