Where to upload animated themes and how to test them locally before upload

more options

Hello,

I read this article about how to create themes: https://developer.mozilla.org/en-US/Add-ons/Themes. How can I test them before upload? I couldn't load them in the browser. On the developer page is no option to upload those files, I am just able to upload 3000x200 pics. How can I upload full/animated themes?

Thanks
