Ruffle - Flash Emulator

Putting Flash back on the web. Designed to be easy to use, this extension will seamlessly enable you to play flash content, with no extra configuration required!

Ruffle - Flash Emulator

Ruffle is a powerful Flash Player emulator that allows you to play Flash content effortlessly in Firefox. With no extra configuration, this extension detects Flash elements on any website and seamlessly upgrades them into the Ruffle player. Not only does it ensure you have the latest features and fixes on sites already using Ruffle, but it also protects you from the security risks associated with Flash, thanks to its foundation in Rust and WebAssembly.

This entirely open-source project is dedicated to preserving internet history by maintaining access to the vast amount of content that relied on Flash. Users are encouraged to contribute in any way, from playing classic games to reporting issues. For more information on how you can support Ruffle, visit ruffle.rs.

it's fucking amazing flash games in 2025


Only works with SWF files. There are sites like ColourLovers.com's pattern generator that use flashplayer for things other than playing flash. Please make the extension also able to handle PNG, BMP, JPG, etc., for generating seamless repeating backgrounds. Thank you! As soon as this happens, 5 stars from me! I'm desperate for this tool!
