rhel7 flash plugin for firefox

I have checked the supp repo for flash for Firefox. All I ever see is the flash plug-in for totem. Am I missing something or is it not there?

These are what I have activated:

Loaded plugins: langpacks, product-id, subscription-manager
repo id repo name status

Also hoping to play MP4 video and MP3 audio.
