About Firefox Extension
Scratch Addons is a browser extension that adds features and themes to the Scratch website and project editor. It is organized around addons, individual features that users turn on and configure through the extension's settings interface, covering things such as a thumbnail uploader, sprite folders, an editor find bar, block editing tools and a project video recorder.
The interface is available in English as well as Spanish, Russian, Japanese, French and other languages. Because it is a browser extension, its features apply to Scratch in the browser and to the project editor there; the homepage presents the extension as free.
