We can test the 0.6.2 version of extension, located at http://www.guillermomolina.com.ar/svn/firefox-kde-wallet/build/kde-wallet_password_integration-0.6.2.xpi
It works for me succesfully: share first saved passwords with konqueror and save other into "Firefox" kwallet folder, because konqueror didn't support store more than one password per url.
