FlashPlayer - SWF to HTML

Open SWF links of Adobe Animate (Flash) in a pure sandboxed JavaScript emulator

FlashPlayer - SWF to HTML: Adobe Flash Emulator Mozilla Add-on

FlashPlayer - SWF to HTML is a Mozilla Firefox extension that brings the capability to playback SWF files originating from Adobe Animate (Flash) within a sandboxed JavaScript emulator. This unique feature eliminates the need for native Flash plugins such as Adobe FlashPlayer. The extension uses the open-source swf2js library as its emulation engine. It offers user-friendly tools to select the right SWF object for playback, safeguards privacy by operating within a private sandboxed window, and provides optional emulation for all embedded flash objects. It utilizes two different engines for operation - Ruffle and SWF2JS.

Add-on summary

Usage Preview: https://www.youtube.com/watch?v=80RWHX9_ZlQ

This extension plays SWF objects of Adobe Animate (Flash) in a pure JS emulator without the need to have a native Flash plug-in like Adobe FlashPlayer. The extension uses the open-source swf2js library as its emulation engine. By default, the extension does not play Flash objects instead, the user presses the toolbar button for the extension to find all available Flash objects or links in the current webpage. It will offer the user to select the proper SWF object and then send the link to a stand-alone emulator window. This way Flash objects are only functioning when there is a request. For Flash links, the extension adds a context menu item to these links so you can directly emulate an SWF link.

Features: Runs a pure JavaScript-based Flash emulator Does not require any native plug-ins Run in a private sandboxed window to protect the user privacy Use two different engines: Ruffle (https://ruffle.rs/) and SWF2JS (https://swf2js.com/) Optionally emulate all embedded flash objects inside the page (use action's right-click context menu)

Notes: This extension uses two open-source emulator engines. The SWF2JS library still does not support all methods available so some SWF objects may crash the engine. The extension always tries to open the emulation window the same size as the actual Flash object, however, you can resize the window to the proper size anytime.
