When I try to upload a file using Firefox, the chooser refuses to open

At least in that case I’ll have a workaround.

This seems relevant:

Browsers like Firefox require xdg-desktop-portal package to use OS default file manager

A known issue previously discussed on this forum is the issue where Firefox (and Chrome?) do not use the default file manager, for example to open folder after a download is completed. All suggestions in those 2 topics to update the mime files have no effect after Firefox or system has been restarted. There is a bug report in the Mozilla bugtracker that contains a solution, for which a package is required: xdg-desktop-portal this package is already installed in a default Manjaro (Gnome) install…

Although this might have already been addressed by recent updates.
