> plugin-container.exe
plugin-container.exe is used for more then just "plugins", so it
may not be abnormal to see it at unexpected times.

also I *think* plugin-container.exe is where out-of-process tabs end up, and Firefox takes screenshots for about:newtab using out-of-process tabs
And there was a related Bug I was looking at... If I come across it...
