手动卸载插件

如果找不到插件的卸载程序，可以用按照以下步骤手动卸载：

1.在地址栏内，输入 about:config，回车；
2.在过滤器那一栏输入 plugin.expose_full_path，就可以看到plugin.expose_full_path这个设置项；
3.双击这个设置项，将值由默认的fale改为true；
4.在地址栏输入 about:plugins，就会列出你目前安装并且启用的插件列表；如果你想卸载某个插件，务必先在工具-附加组件-插件中启用它；
5.每个插件名底下都有对应的路径（步骤3的设置就是为了显示这个路径），打开资源管理器找到插件对应文件；
6.将插件对应的文件重命名，比如Mozilla Default Plug-in对应的文件npnul32.dll，将它重命为Xnpnul32.dll;

刷新一下about:plugins页面，你会发现对应的插件已经被卸载了。

5.再打开配置文件夹你会发现一个新的pluginreg.dat。
