Ruffle - Flash Emulator v0.1.0.1381 
Ruffle will detect all existing Flash content on a website and automatically "polyfill" it into a Ruffle player, allowing seamless and transparent upgrading of websites that still rely on Flash content.
If websites also have Ruffle installed, this extension will upgrade it to the latest version if needed. By installing this extension, you get access to the latest fixes and optimisations even on websites that already include an older copy of Ruffle, whilst also providing you with some extra options.
Ruffle is a Flash Player emulator written in Rust. Ruffle runs on all modern browsers through the use of WebAssembly. Leveraging the safety of the modern browser sandbox and the memory safety guarantees of Rust, we can confidently avoid all the security pitfalls that Flash had a reputation for.
Ruffle is an entirely open source project maintained by volunteers. We're all passionate about the preservation of internet history, and we were drawn to working on this project to help preserve the many websites and plethora of content that will no longer be accessible when users can no longer run the official Flash Player. If you would like to help support this project, we welcome all contributions of any kind - even if it's just playing some old games, seeing how well they run, and letting us know any issues you find!
