browser-compat-data - This repository contains compatibility data for Web technologies as displayed on MDN

•    Javascript

This repository contains compatibility data for Web technologies. Browser compatibility data describes which platforms (where "platforms" are usually, but not always, web browsers) support particular Web APIs. This data can be used in documentation, to build compatibility tables listing browser support for APIs. For example: Browser support for WebExtension APIs.

webextensions-examples - Example Firefox add-ons created using the WebExtensions API

•    Javascript

Maintained by the MDN team at Mozilla. WebExtensions are a way to write browser extensions: that is, programs installed inside a web browser that modify the behaviour of the browser or of web pages loaded by the browser. They are built on a set of cross-browser APIs, so WebExtensions written for Google Chrome or Opera will in most cases run in Firefox or Edge too.
