Or others that can be found by searching with keywords like "KDE Firefox mime".
In the mean time, here is a possible workaround from Canonical support:
1) stop firefox
2) rm ~/.mozilla/firefox/<profile>/mimeTypes.rdf
3) start firefox
4) download a file
5) open it from the downloads menu and choose the application. Browse to /usr/bin/xdg-open. then check to remember your choice
Now both open and open containing folder should work. You can then change the preferred programs through kde's file associations settings.
