Yesterday I spent 10 minutes throwing together an example WebExtension to show how a few APIs worked. It's not a complicated or sophisticated one by any means, it just shows a pop-up and links to trigger some tab APIs.

But when writing an add-on like that, you might notice a few things:

• Thanks to about:debugging you can load the add-on straight from the directory and run it. There is no xpi, zip or compile step. It just works.

• The menu is a html page with some JavaScript on it. That's familiar territory for any web developer.

• The HTML and Javascript reload each time I make a change. That's refreshingly simple and easy to develop with.

Those factors alone make developing that add-on so much easier than before. We are getting there.
