Installation of Ruffle in the browser of choice adds Flash emulation to the browser. What is interesting about Ruffle is that its developers have created browser extensions for Firefox, Chromium-based browsers such as Chrome, Edge, Brave, Opera, or Vivaldi, and for Safari. The Internet Archive uses an emulator that is called Ruffle the emulator is written in Rust and it supports all modern operating systems and modern we browsers that support WebAssembly. Examples are the Flash Games Preservation Project that preserves hundreds of Gigabytes worth of Flash content, specifically games, and the Internet Archive, which makes Flash content playable in an emulator on the archive's website. One option comes in the form of preservation projects. Major browsers such as Chrome, Edge or Firefox won't support Flash either anymore, and these decisions lead to a question that none of the decision makers have provided an answer for: what if a user needs to access Flash content after 2020, and what happens to Flash content that is still available on the Internet as it won't just vanish when the technology is disabled? Adobe Flash will no longer be supported in 2021 Adobe released the final Flash update in December 2020 and announced that it will disable Flash functionality in 2021.
