firefox的plugin-container进程关闭方法

http://kb.mozillazine.org/Plugin-container_and_out-of-process_plugins

 

Disabling crash protection

  go to about:config and set all dom.ipc.plugins.enabled.* preferences to false. This will prevent the "plugin-container" process from running and all plugins will run within the Firefox browser process.

On Linux:

dom.ipc.plugins.enabled.libflashplayer.so (Adobe Flash)

dom.ipc.plugins.enabled.libnptest.so (NPAPI test plugin)

On Windows:

dom.ipc.plugins.enabled.npctrl.dll (Microsoft Silverlight)

dom.ipc.plugins.enabled.npqtplugin.dll (Apple QuickTime)

dom.ipc.plugins.enabled.npswf32.dll (Adobe Flash)

dom.ipc.plugins.enabled.nptest.dll (NPAPI test plugin)

Toggle (double-click) each preference to change the value from "true" to false.

firefox 4 beta13pre 中，只需要设定一项内容足够了，如下user.js片段所示。
//关闭plugin-container进程
user_pref("dom.ipc.plugins.enabled", false);
