In Fx3 enter the following in the url bar:

about:plugins | Enter

That will show you each plugin that is installed. Now to fine the Totem
plugin (for instance) you'll see that the file name is

That will show you where the actual plugin is located.

If you are using a combination mplayer/realplayer:
