Flash Player 7--installed but doesn't work

[Alexander Sukhodolsky <umdsasha gmail com>]

I downloaded flash 7, untarred (xvf) and, as root, installed into (when it prompted): /usr/lib/mozilla

this has always worked for me in previous fedora cores, yet i get no results--how am I to view 
homestarrunner.com?! ;)

I read that /usr/lib/mozilla is the global folder for all plugins (that is, the plugin folder in there is global and thus firefox will access it for plugins), but I get nothing.  When I view firefox plugins, I see only the realplayer one.
