Firefox getting worse and the workarounds for it

• In Firefox 152, Mozilla disabled the ability to confirm file downloads or uploads by pressing the Enter key on Linux to patch a clickjacking vulnerability. In about:config, set widget.use-xdg-desktop-portal.file-picker=1 to fix. In doing so they also broke keyboard navigation (e.g. enter to change directory). This seems restored in openSUSE's Firefox 154.
