Windows Media Player DLL is busy or not responding.

When I attempt to open a web page with Windows Media Player embedded, Firefox locks up for about 30 seconds, then a message appears that says "Windows Media Player is busy or not responding."

It offers to let me continue waiting, or stop the DLL.

If I continue waiting, the page eventually loads, and Firefox wakes up.

The embedded media player has a gray background and nasty-looking circa 1998 controls. (It used to have contemporary controls, resembling stand-alone media player.)

Embedded media player still works correctly with Internet Explorer, and shows the correct controls and user interface.

I've already set plugins.load_appdir_plugins to true - that wasn't it.

This seems to be a recent issue - earlier versions of Firefox handled the embedded media player fine.

I have npdsplay.dll version 3.0.2.629 and np-mswmp.dll 1.0.0.8 installed.

Thanks.

Hello JacksBack,

Some plugins that are no longer maintained, like the Windows Media plugin, have their files installed in a place that Firefox no longer supports.

Please refer to:

Windows Media or other plugins stopped working after Firefox update

You do have some addons that could cause general problems with pages like Adblock Plus and Ghostery, have you tried disabling all the addons in safe mode yet.
