Steps to reproduce:

Right-click on any image and select Save Image As using the flatpak version of Firefox on the Valve Steam Deck.

Actual results:

Nothing.

This is a bug that has happened before in the flatpak. It was fixed a few versions back and saving images worked again, then a Firefox update broke it again, and it has never worked again since.

Expected results:

One of two things should have happened, it should have either automatically downloaded the image file to the pre-configured download folder, or with the checkbox selected "Always ask you where to save" should have popped up a dialog.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

The Save image As.. should always show the file save dialog. The dialog is implemented in the xdg-desktop-portal backend. In case of Gnome, it's xdg-desktop-portal-gtk. Most likely it's a bug in the Valve Steam Deck, something like: https://github.com/ValveSoftware/SteamOS/issues/1007

In the current release of Firefox flatpak, save-image-as is working through the portal so I will go ahead and close the bug.
