Replace Adobe Flash Player with Ruffle Flash Emulator on Windows

Ruffle is a flash emulator for all the popular platforms as well as web browsers. It is designed using the Rust programming language and handles all the memory management successfully unlike the Adobe Flash Player. It is available for Windows, Linux, Mac as desktop application. It is available as an extension for Firefox, Chrome, Edge and Safari browsers.

Now that Adobe Flash Player has been discontinued starting from January 1st, 2021, you can replace it with Ruffle Flash Emulator and continue to use all the flash content just like before. First thing that you have to do is to remove Adobe Flash Player from your Windows PC.

Once you have removed Adobe Flash Player, you can install Ruffle on your Firefox or Chrome browsers in form of the browser extension. Since the Ruffle extension is still under development it is unsigned and not available from the Mozilla site. For installing Ruffle in Firefox, you have to follow these steps:

  1. Install Firefox Nightly browser (because only it allows unsigned extensions) from
  2. Launch Firefox Nightly, type about:config in the address bar and proceed to find a setting labeled xpinstall.signatures.required. You have to change its value to false.Ruffle for Firefox

The desktop version of Ruffle comes in form of a command line program. You have to run it with the flash file as the argument. For example, if you want to play the yahootennis.swf game then you have to give the command ruffle.exe yahootennis.swf. This will launch the Flash content in a new Ruffle window.
