I believe that each user has a profile. So in your new guest account, you may have a .mozilla directory. Check with your regular account to verify this. Underneath it, it might have a folder called plugins. Put the Flash library plug-in into this directory, restart firefox, and your problem is solved. I've noticed that some distros do this. Not sure why.
What I do with my awesome CentOS is just directly put the Flash plugin into the Firefox directory so that all my accounts will have Flash.
