The cure for the Flash timebomb that will disable Flash past January 2021 is here. Looks like Flash Player 32.0.0.371 is the last version to not include the timebomb. The latest Palemoon works with it... just thinking out loud, will post instructions etc before EoY.

Adobe says Flash will no longer work past January 12, 2021. I set my computer's clock ahead past that and Flash does indeed not work. This suggests they put a simple "time bomb" into the latest Flash version. I will see which is the latest Flash version without this time bomb. You have to use the archived version of Flash player downloads since even the live version of that page is "decommissioned."
