Changes

If you're already familiar with add-on development or you think you're a good technical writer, help us improve the WebExtensions API reference documentation on [MDN](https://developer.mozilla.org/Add-ons) or the Firefox-specific documentation for add-on developerson [Extension Workshop](https: //extensionworkshop.com). The list of open issues for Extension Workshop can be found on in the [extension-workshop repository](https://developergithub.com/mozilla.org/enextension-USworkshop/Add-onsissues) on Github.

You can also help by translating these docs on MDN to a different language (pro tip: try replacing the en-US part of the link above to your native language code).
