Take the 2-minute tour ×  I want to use KDE file dialogs (file
open, file save) in Firefox in Kubuntu 12.04.  This requires
something like the ancient KGtk script, but for KDE 4.x and
recent Firefox versions.  OpenSuse offers this kind of
functionality. Kubuntu dropped it, but surely someone has worked
on bringing this back to Kubuntu (I hope).  Note, I'm not asking
about theming/looks. I'm asking about actually using KDE file
dialogs instead of XUL or GTK dialog.  And the preference
ui.allow_platform_file_picker doesn't affect this. I have
already tried setting it to true and false. Neither options
results in using KDE dialogs.   share|improve this question  3

Kubuntu 12.04 (other KDE distros are supported too -
