火狐安装插件
So you just bought a training video and popped it into your computer. You click on the menu in the autoplay dialog and it opens up Firefox, your default browser. Now you are staring at a blank screen. What now?
因此，您刚刚购买了一个培训视频并将其弹出到计算机中。 您单击自动播放对话框中的菜单，它将打开默认浏览器Firefox。 现在，您正盯着黑屏。 现在怎么办？
The problem is most likely because you don’t have the Windows Media Player plugin installed for Firefox, so all we need to do is install it.
问题很可能是因为您没有为Firefox安装Windows Media Player插件，所以我们要做的就是安装它。
Note that you’ll usually have the same problem anytime you try and view video files in FIrefox using Windows Media format, such as .wmv files.
请注意，每次尝试使用Windows Media格式查看FIrefox中的视频文件(例如.wmv文件)时，通常都会遇到相同的问题。

Verifying Plugin Installation
验证插件安装
After running through the very quick installation wizard, you might be curious if the installation actually worked. While the easiest method is to just open a Windows Media video, you can also type the following into the address bar to see the list of loaded plugins:
通过非常快速的安装向导运行后，您可能会对安装是否确实有效感到好奇。 尽管最简单的方法是仅打开Windows Media视频，但您也可以在地址栏中键入以下内容以查看已加载插件的列表：
about:plugins
关于：插件
And you should see the Windows Media Player plugin in the list. You can also see which file types Firefox will use the plugin on.
并且您应该在列表中看到Windows Media Player插件。 您还可以查看Firefox使用插件的文件类型。
And now I can view this Windows Media format video file in Firefox…
现在，我可以在Firefox中查看此Windows Media格式的视频文件…
Technical Notes
技术说明
In case you have any issues with this installer, you might want to take a look at this list to help with your troubleshooting:
如果您对此安装程序有任何疑问，则可能需要查看以下列表以帮助进行故障排除：
- The WMP plugin uses the IE Proxy settings, not the ones in Firefox. This is because the plugin itself is only a thin wrapper around Windows Media Player, which always uses IE internally to fetch data. WMP插件使用IE代理设置，而不是Firefox中的设置。 这是因为插件本身只是Windows Media Player的一个薄包装，后者始终在内部使用IE来获取数据。
- The plugin files are installed to the “C:\Program Files\Mozilla Firefox\plugins” directory by default, and the file name is np-mswmp.dll. If the uninstaller fails to remove this file for whatever reason you can manually delete it. 插件文件默认安装在“ C：\ Program Files \ Mozilla Firefox \ plugins”目录中，文件名为np-mswmp.dll。 如果卸载程序由于某种原因未能删除此文件，则可以手动将其删除。
- You could also theoretically copy the same .dll file into the plugins directory on any Firefox installation and it should work without running the installer. 从理论上讲，您也可以将相同的.dll文件复制到任何Firefox安装中的plugins目录中，并且无需运行安装程序即可正常工作。
