Do any actions that call a system file browsing window work? For example:

• the Browse... button below this text box when composing a reply
• (menu bar) File > Open File...
• right-click a page > Save Page As...

If not, it could be the issue mentioned in this thread:

Try downloading Firefox from Mozilla, run it from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release Are you on X11 or Wayland?

I installed "xdg-desktop-portal and xdg-desktop-portal-gtk" but still I can't Download ;(

I fix it!!

You can check for issues with "xdg-desktop-portal" and possibly install some packages.

• sudo apt install xdg-desktop-portal 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
