Configuring konqueror for flashplayer

I went to www.theinquirer.net. Konqueror asked me how to open a .swf file. I checked the "do not ask again" box and looked for an application to open it with. By mistake, I selected konqueror as the application. How can I undo what I have done? In the first place, why did konqueror not open the .swf using /usr/lib/browser-plugins/libflashplayer.so?
