adobe flash

Content that used to be presented with [proprietary] Flash, and needed an add-on, has been replaced by standard H.264, that has built-in support in all modern Browsers and email readers.

Any web site that has not made the transition has made a decision not to remain in business.

Whoever hosts or developed the assignment will have to upgrade their app/product. No one supports Flash any more.

There is no need to replace Flash Player. Flash content no longer is supported.
