Flash content in ebooks after 2020


I am aware that the major browsers are not going to support flash player from 2020. I have some ebooks with flash content. Will this content still be playable in the ebooks after 2020?

Kind regards,


Old ebooks will still work provided that the Flash player (which is installed by default on recent Windows) is installed. Ebooks made with HTML EXE 4.x use the Trident engine which shouldn’t be impacted.
