The computer software company had already stated that they will no longer support the Flash Player with updates in 2017, and now they've confirmed that after December 31, it will reach the end.
In a notice on their website, Adobe explained: "As previously announced in July 2017, Adobe will stop distributing and updating Flash Player after 31 December 2020 ("EOL Date"). We made this announcement in collaboration with several of our technology partners - including Apple, Facebook, Google, Microsoft and Mozilla - which issued complementary announcements with more technical detail on what the Flash Player EOL will mean for developers, enterprises, and consumers using their specific OS environments or browsers.
Adobe gave three years' notice to the likes of Apple, Facebook, Google and Microsoft so they could "migrate existing Flash content as needed to new, open standards".
On why they chose the aforementioned date, they added: "Open standards such as HTML5, WebGL, and WebAssembly have continually matured over the years and serve as viable alternatives for Flash content.
"Also, the major browser vendors are integrating these open standards into their browsers and deprecating most other plug-ins (like Adobe Flash Player).
"By announcing our business decision in 2017, with three years' advance notice, we believed that would allow sufficient time for developers, designers, businesses, and other parties to migrate existing Flash content as needed to new, open standards."
Security fix, OS maintenance, browser compatibility and more will be issued throughout 2020.
However, after December 31, the Flash Player will be removed.
The firm has warned people not to download Flash Player from third parties.
