Adobe has now removed all support for flash and are together with other operators blocking the use of flash. I have installed Ruffle which is intended to keep flash applications running. It is not yet working well in all cases. Ruffle is not yet supporting AS3 and even on the applications that it works on it opens the application very slowley. Hopefully it will become better in time. - 2021-01-17

Except for "Tada" all applications on this page are flash applications.
