Flash (officially) "died" some time ago...
On July 25, 2017, Adobe announced that they planned "end-of-life" for Flash by the end of 2020. This was published by Adobe, in a post titled "FLASH & THE FUTURE OF INTERACTIVE CONTENT", in their news blog "Conversations".
Relevant quotes from the aforementioned post:
"(...) as open standards like HTML5, WebGL and WebAssembly have matured over the past several years, most now provide many of the capabilities and functionalities that plugins pioneered and have become a viable alternative for content on the web (...)"
"(...) Given this progress, and in collaboration with several of our technology partners – including Apple, Facebook, Google, Microsoft and Mozilla – Adobe is planning to end-of-life Flash. Specifically, we will stop updating and distributing the Flash Player at the end of 2020 and encourage content creators to migrate any existing Flash content to these new open formats. (...)"
It was not necessary to wait until 2020: it was already happening...
Mobile Web browsers, almost all of them, only supported HTML5.
Desktop Web browsers began blocking Flash by default, in favor of HTML5:
- Chrome, since version 55 (released in December 2016).
- Edge (Windows 10), since the updated released with the "Creator's Update" (released at the beginning of 2017).
- Firefox will did it later.
