Very usefull addon, but there's one problem with auto-lock (and also auto-logout probably) - when I'm playing flash game or watching flash video, MP+ doesn't indicate activity -> It locks automatically after set up delay

That is limitation of Firefox + Flash. Flash is external application running inside Firefox. Nothing can be done about it.
