Is there an official Video Speed extension for Firefox?

I noticed a new extension: [Video Speed Controller](https://addons.mozilla.org/en-GB/firefox/addon/videospeedcontroller/) by [Igrigorik](https://addons.mozilla.org/en-GB/firefox/user/19548649/) has been added recently to Firefox add-ons but haven't found any mention of it in the repo. @igrigorik just wondering if you've released a Video Speed extension for Firefox?
