Adobe will start blocking Flash content until January 12th. Major browsers will shut it all down tomorrow and Microsoft will block it in most Windows.
Browsers started showing flash the door early in the last decade. In 2015 Adobe asked developers to move on to HTML5. Things became official in 2017, when Adobe announced it would end support.
The Internet Archive is preserving Flash games and animations, including well-known hits like’peanut butter jelly time’. Adobe is finally letting flash go, but it will live on in many historical artifacts.
