Every time i try to use flash and go through the hassle of GETTING IT TO PLAY

i’m sorry but i am just a little bit tired and just to watch in private a video that uses Flash HOW CAN I GET IT TO Save to use it? I have to wear a mask that is unhealthy ALL DAY LONG NOW AND FOR THE REST O F OUR LIVES AND USING FLASH isn’t that bad at all…or is it.
