With some reflection, I realized Firefox is launching the KDE file picker portal and not the generic Qt. I was fooled by this because the dialog was opening with all of the generic flat icons and did not look like the normal KDE file picker I had configured in my KDE environment. The xdg-desktop-portal-tde.desktop is installed in /opt/trinity/share/applications rather than /opt/trinity/share/applications/tde like all other TDE desktop files. The org.freedesktop.impl.portal.desktop.tde.service file is installed in /usr/share/dbus-1/services, the same place as org.freedesktop.impl.portal.desktop.kde.service. The tde.portal file is installed in /usr/share/xdg-desktop-portal/portals, the same as the kde.portal file. The tde.portal file has UseIn=Trinity where the kde.portal has UseIn=KDE. I do not think 'Trinity' is a valid XDG reference and the key should be UseIn=TDE. The sources show UseIn=Trinity and should be patched to UseIn=TDE. Refer to https://specifications.freedesktop.org/menu-spec/latest/onlyshowin-registry…. I changed UseIn=Trinity to UseIn=TDE. Initially that did not seem to do anything because when I launched Firefox the KDE portal launched. More on that change later. Next I moved xdg-desktop-portal-tde.desktop to /opt/trinity/share/applications/tde/. Moving the file made no difference. I terminated Firefox and killed all portal processes each time. Next I killed the portal processes while leaving Firefox running. I launched /usr/libexec/xdg-desktop-portal --verbose. The output spew showed that xdg-desktop-portal had selected the TDE portal for the file picker ("Using tde.portal for org.freedesktop.impl.portal.FileChooser in TDE"). The process list showed both the KDE and TDE portals. I tried to use Firefox File-->Open and the TDE file picker dialog opened. I closed Firefox and killed the portal processes. I launched Firefox and again killed the portal processes. I manually launched /usr/libexec/xdg-desktop-portal but not verbose. I launched Firefox and again the TDE file picker opened. I closed Firefox and killed the portal processes. I manually launched /usr/libexec/xdg-desktop-portal without verbose and as a background process. The process list showed both the KDE and TDE portals. I launched Firefox and the TDE file picker dialog was used. I created a $TDEHOME/Autostart desktop file to force launch /usr/libexec/xdg-desktop-portal. After starting my TDE session, the process list showed the TDE portal. Again Firefox used the TDE file picker. Seems when xdg-desktop-portal is manually launched before launching Firefox then everything behaves as expected. Having Firefox launch xdg-desktop-portal fails to call the TDE portal. I removed the temporary autostart file. Although Firefox had widget.use-xdg-desktop-portal.file-picker=1, just to be sure, I toggled all other widget.use-xdg-desktop-portal.* options to 1. I then renamed kde.portal to kde.portal.bak. I logged out and restarted TDE. I verified no portal processes. I launched Firefox and saw that there was no kde portal process and the tde portal process was running. Firefox then used the TDE file picker. Some more trial-and-error testing indicates UseIn=TDE does need to change in the sources. Although the TDE portal will launch manually and everything behaves, seems KDE is receiving priority over TDE when both portals are available. I don't know where the mixup might be. Could be me. Could be Slackware. Could be TDE. Could be something else. I think the TDE portal package is fine. One way or another something is awry. I hope the information helps. Any feedback is welcomed. :)
