Unable to access Flash settings when righ clicking on Flash logo at Adobe flash web page.

I am trying to disable hardware acceleration for Adobe Flash player because I am no longer able to enlarge videos in Firefox(Note, I can still enlarge in Edge).  I am running the latest version of Firefox, and Windows 10.  Advice I have seen thus far recommends disabling hardware acceleration as a first troubleshooting step by navigating to the Adobe flash help webpage, righ clicking on the Flash logo and selecting "settings".  When I right click on the logo, however, there is no "settings" option to select.  How can I alternatively access Flash settings so that I can disable hardware acceleration?
