Question & Answer
Question
I still can't get my audio to play after installing QuickTime 7.7.9 on Mozilla Firefox. What do I need to do to get this to work?
Cause
The QuickTime browser plug-in needs to be added.
Answer
If you are installing QuickTime 7.7.9 or above you should select the "Custom" install option instead of a "Typical" install, so that you can include the optional QuickTime Web Plug-in. If you have already installed or updated QuickTime, you can add the browser plugin using these steps:
1. Find the QuickTime Installer file you downloaded previously and double-click it. (Alternatively, open the Windows Control Panel, choose Programs, then Programs and Features, select QuickTime from the list of installed programs and click Change.)
2. In the "QuickTime for Windows" window that opens, select Modify.

3. In the "QuickTime Product Features" window, choose Optional QuickTime Features and, under QuickTime Web Plug-in chose the drop-down option, Entire feature will be installed on local hard drive.

4. Click the Change button.
The QuickTime installation will complete and the browser plugin will be installed. If you see an installation error, close Firefox (if open) and try again. When you next open Firefox you should see the QuickTime plugin listed in the Add-ons Manager.
