alternative for flash

Edit: I found a website which installs Ruffle extension in your browser and Ruffle therefore plays Flash videos directly from the browser. I have not tested it myself, so give it a try yourself: https://www.ghacks.net/2020/12/17/how-to-play-flash-content-in-your-browser-in-2021/

I've already tried it, says Ruffle does not yet support ActionScript3, whiich is required.
