I have a Windows XP running in a virtual machine and lately I saw this machine running on 100 percent usage while browsing the web with firefox 3.6.12. I looked in the task manager and found a process named plugin-container.exe slowing down my system with nearly 65 percent system usage. Thats not nice to browse with. But I managed to get rid of it.

This process comes from firefox and is there to prevent the browser hang up, if any plugin is crashing. So you should not deactivate it unless you have a good reason for it, like me.

So here is, how I managed to deactivate it in firefox.

  • Open a new tab and go to about:config
  • in the filter bar type „dom.ipc.plugins.enabled.npswf32.dll“
  • double click the entry to change it from true to false
  • restart firefox and be happy
That’s it.
