User reviews
Pros
- Allows playing SWF/Flash content within Firefox.
- Generally works well with many SWF files and Flash games.
- Includes a feature to convert SWF to JavaScript (SWD2JS engine).
- Enjoyed for enabling playback of Flash games and animations despite Flash's discontinuation.
Cons
- Does not automatically play embedded SWF files; requires manual activation.
- Incomplete support: does not work for all Flash games, especially those on certain sites like Kongregate and pet sites.
- The SWD2JS engine is a clone of the Ruffle engine and lacks ActionScript 3 support.
- Some SWF files (like those on specific websites) fail to load or display properly.
