(In reply to PhobosK from comment #36) I've seen the same issue in Fedora. My workaround was to "sabotage" the org.freedesktop.Filemanager1 dbus service by creating ~/.local/share/dbus-1/services/org.freedesktop.FileManager1.service and changing the Exec line to e.g. /usr/bin/false or /usr/bin/true; this is better since it's persistent and isn't affected by system updates... etc. This makes Firefox use whatever file manager I set in ~/.local/share/applications/defaults.list (see comment #31).
Changing Exec to /usr/bin/dolphin somehow made "open containing folder" open the file manager, but the firefox UI gets sort of blocked/hung for a while, probably because firefox tries to query the capabilities of org.freedesktop.FileManager1 via dbus first, (just a guess).
