The solution I found is to launch this command in the terminal:
WARNING: IT WILL RESET ALL YOUR SETTINGS AND WILL LOG OUT FROM ALL SITES. IT WILL BE RESETTED LIKE AFTER THE INSTALLATION
flatpak override --user --filesystem=home org.mozilla.firefox

Would be possible to add this feature at build time? I mean for the common user it's just impossible to think that can find this solution and run it in the terminal

When a file is drag-and-dropped, the compositor will send an event with a path to the file in the host.
Sandboxed applications can't read this path, since they don't have filesystem access on the host, so the reading the dropped file fails.
This requires compositors to integrate with the xdg-document-portal. There's an issue for this for sway: https://github.com/swaywm/sway/issues/6460
In the meantime, I don't think there's anything Firefox can do to support this.
flatpak override --user --filesystem=home org.mozilla.firefox
Note that this pretty much negates the usefulness of the sandbox; Firefox can read and write any file in your home (including ssh keys, etc), and alter .bashrc and friends to hijack sessions entirely.
In Firefox Drag & Drop works from files within the Download directory.
I don't think there's anything Firefox can do to support this.
Something regarding this was merged into xdg-desktop-portal in 2019:
https://github.com/flatpak/xdg-desktop-portal/issues/99#issuecomment-565043646
And it was said that Gtk4 apps should have support for this out of the box support according this comment: https://github.com/flatpak/xdg-desktop-portal/issues/99#issuecomment-565264246
So maybe it needs the same or similar logic in FF?

Re-triaging because this is most likely due to Flatpak's sandboxing not punching a hole for the file rather than anything DOM related.
