trying to open a audio/x-mpegurl opens the missing plugin window.
The plugin-finder-service opens  www.microsoft.com, very helpfull with linux.
In tools->options you forgot the "add" or "new" button to add a new mimetype. So some mimetypes are impossible to handle with firefox for me.

Reproducible: Always

1.go to e.g. www.medionmusik.de
2.try to listen to a song
3.get ****
Actual Results:  
missing plugin is displayed, clicking on install leads to www.microsoft.com

Expected Results:  
find a working plugin or opens a window to choose an application to open the file/stream with
