No, Firefox DevTools are not Firebug. The web came a long way since Firebug, and so have the DevTools baked into Firefox. So let's go exploring!

As the complexity of the web apps you build keeps moving, so do the Firefox DevTools.

In this session, Alex will give you the latest tips and tricks on Firefox DevTools. We'll explore new and less commonly known features in performance profiling, JavaScript debugging and animation inspection. The session will give you a productivity advantage when developing and debugging your web applications.

There is a new, Blink-compatible API in Firefox called WebExtensions. Extension code written for Chrome, Opera, or, possibly in the future, Microsoft Edge will run in Firefox with few changes as a WebExtension. It will be shown how to use this API to develop addons for Firefox OS.

For some time we’ve heard from add-on developers that our APIs could be better documented and easier to use. In addition, we’ve noticed that many Firefox add-on developers also maintain a Chrome, Safari, or Opera extension with similar functionality. We would like add-on development to be more like Web development: the same code should run in multiple browsers according to behavior set by standards, with comprehensive documentation available from multiple vendors.

To this end, we are implementing a new, Blink-compatible API in Firefox called WebExtensions. Extension code written for Chrome, Opera, or, possibly in the future, Microsoft Edge will run in Firefox with few changes as a WebExtension.
