Hello,

First you have two Adobe Shockwave for Director Netscape installed in your computer, the difference is the version:

• Adobe Shockwave for Director Netscape plug-in, version 12.0.7.149
• Adobe Shockwave for Director Netscape plug-in, version 12.0.7.148

So try check your drives and also try disable the hardware acceleration:

• Upgrade your graphics drivers to use hardware acceleration and WebGL
• Check plugins

The plugin only stops, doesnt show any message?

Note that you shouldn't confuse the Shockwave Flash plugin and the Shockwave for Director plugin as that are plugin for different content.

Does the Adobe test page still work?

Note that you can get a possibly colored Lego icon on the left end of the location bar that indicates that Firefox is blocking a plugin.

I found it had to do with unsecure content on the webpage. When you click on the shield icon on the left end of the location bar, one of the options in the dropdown is to allow/display the unsecure content. This worked for me. The flash Player displayed and I was able to play the video.
