Firefox 4.0 disabling plugin-container.exe fix (English)

On Firefox 3.6.4 plugin-container appears first time. See http://alexsmail.blogspot.com/2010/09/firefox-how-to-disable-plugin.html You can find how disable it theire too.

It appears, that it was sort of undocumented feature, so in Firefox 4.0 you should disable it again (and remove some garbage in the configuration). I updated the link above, it contain the update for Firefox 4.0, but I want to duplicate it here for those who disabled plugin-container in version 3.6.

* Go to about:config
* In the Filter field type dom.ipc.
* Change value of dom.ipc.plugins.enabled to false.

On Firefox 4.0.x you can have some garbage settings:



For evey entry in the list dom.ipc.plugins.enabled.npctrl.dll, dom.ipc.plugins.enabled.npqtplugin.dll, dom.ipc.plugins.enabled.npswf32.dll, dom.ipc.plugins.enabled.nptest.dll (these are garbage to be cleaned) do the following:

- Right Click on it;
- On the menu click on Reset;
- Restart your browser (you can do it later)
- Check that these setting are gone.
