"plugin-container" is a core part of Firefox, and Firefox will not work if it is blocked.

(plugin-container is a separate process used to isolate crashes in web content, part of the Crash Protection feature in recent versions of Firefox.)

Thank you =) So, really, when McAfee did what I said (block the plug-in container) I disabled Firefox ... or I made McAfee disable Firefox. End result was Firefox couldn't work at all.

how do i unblock it then?
