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.
