"File exporer" window doesn't open
I want to attach a file and I click on a button (everything works perfectly on Chrome). When I click, in the console I get this error:
(firefox:3264): Gtk-WARNING **: 13:52:46.781: Can't open portal file chooser: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: L’interface « org.freedesktop.portal.FileChooser » n’existe pas pour l’objet à l’emplacement /org/freedesktop/portal/desktop
Of course, nothing happens when I click.
I have Ubuntu 22.04 and apparently Firefox in installed with snap, and I have this problem since snap is used to install Firefox.
If it's useful:

This message is the last I'm writing before I definitely move to Chrome. I hope I'll get the help I couldn't find on other places (I saw a lot of answers telling to deactivate snap, adding a ppa or some solutions like these).

Snap has restrictions when it comes to file access.
You can try Firefox from the official Mozilla server if you currently use a version from the repositories of your Linux distribution to see if it behaves differently.
On Linux this can be an issue with "xdg-desktop-portal" and you may have to install some packages like xdg-desktop-portal and xdg-desktop-portal-gtk. Whether to use gtk portal for the file picker. 0:never 1:always 2:auto (true for flatpak or GTK_USE_PORTAL=1, false otherwise)
- about:config => widget.use-xdg-desktop-portal.file-picker = 0

Thanks for your answer. Actually I installed everything related to the problem I encountered:
sudo apt update && sudo apt-get install --reinstall xdg-desktop-portal-gnome xdg-desktop-portal-gtk xdg-desktop-portal-tests xdg-desktop-portal
What are you suggesting? That I change the value ("2", for the moment) of the variable to "0"?
I tried to uninstall firefox from snap and install it using the PPA, but for some reason it has updated (I don't know when because I sudo upgraded blindly) using snap. I tried methods indicating how to get rid of snap but for some reason it caused more harm (at some point I couldn't remove firefox from snap...).
The default behaviour for installing firefox on ubuntu 22.04 is snap. I think that's a terrible idea if snap has restrictions. I asked colleagues and the ones who encountered the same problem told me they switched to Chrome because maintaining Firefox usable in Ubuntu required too much effort. I begin to understand why...

I would like the steps taken to see if I can replicate the issue, but need help trying to understand what exactly you're doing. Steps to replicate and screenshot please.
