How do I get Firefox with QuickTime to play sounds in Wolfram|Alpha?
- Windows XP
- Windows Vista
Occasionally, when using Firefox and QuickTime, you will get corrupt .dll files in your browser's directory. Simply reinstall the latest version of QuickTime, which will reset the necessary browser plug-ins.
Or 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 npqtplugin.dll, npqtplugin2.dll, npqtplugin3.dll, npqtplugin4.dll, npqtplugin5.dll, npqtplugin6.dll, and npqtplugin7.dll.
- Open QuickTime and reassociate MIDI files with your browser plug-in. See the instructions here.
