An extension adds features and functions to a browser. It's created using familiar web-based technologies — HTML, CSS, and JavaScript.

We’ll be meeting here to discuss the current state of WebExtensions (new APIs, toolings, and more). Whether you’ve authored several web extensions or a newbie working on your first extension, all are welcome to join and share about your experiences of building web extensions!

This session will be hosted by Danny Colin, with representatives from Mozilla Firefox’s add-ons team (Rob Wu & Simeon Vincent), from Google Chrome's extensions team (Oliver Dunk), and other extension community members ready to answer your questions.
