How do I get Firefox with QuickTime to play my WolframTones compositions?
Occasionally, when using Firefox and QuickTime you will get corrupt .dll
files in your browser's directory. To fix this you can remove the plug-in
files and reassociate QuickTime with MIDI files.
- Shut down any running instances of Firefox and QuickTime.
- Open up My Computer and navigate to
C:\Program Files\Mozilla Firefox\plugins
- Delete npqtplugin2.dll and npqtplugin.dll.
- Open up QuickTime and reassociate MIDI files with your browser plug-in.
