Hi, I have installed the Adobe Flash multiple times, uninstalled and reinstalled Firefox, restarted my computer a dozen times and I can't get this video to work in Firefox: http://tv.adobe.com/watch/make-it-with-creative-cloud/hit-the-runway-with-creative-cloud/ It's from adobe's own website. I click "run flash" and the video window is just a blank black box. This makes no sense. The flash website shows that I have flash installed. I have the plug-in set to "ask to activate". I activated it and it doesn't work on that website. It's driving me crazy! I'm running Firefox Quantum 58.0.1 Flash 28.0.0.137 Thanks.
