What program will substitute Adobe Flash Player?

In July 2017, Adobe announced[15] that it will end support for Flash Player on December 31, 2020, and continued to encourage the use of open HTML5 standards in place of Flash.[16][17] The announcement was coordinated with Apple,[18]Facebook,[19] Google,[20] Microsoft,[21] and Mozilla.[22] All major web browsers plan to officially remove Adobe Flash Player on December 31, 2020, and Microsoft will be removing it from the Windows OS entirely in January via Windows Update.[23]
