You know how each browser used to have totally different technologies for making add-ons or extensions. (They weren’t even called the same thing.) And how more recently, several browsers totally changed their extensions to use a similar set of APIs as the others? Yeah. That.

Now it’s official. There’s now a WebExtensions Community Group, initiated by Apple, Google, Microsoft and Mozilla, for aligning on a common vision for browser extensions and to work towards future standardization. w3.org/community/webextensio… Web standards. For extensions.

If you’ve been considering an idea for an extension but hadn’t made it yet, now is a great time. It’s easier than it’s ever been to make one extension, one code base & ship it to all the browsers. And it will just keep getting easier over the next year / going forward.

If you have an extension that runs in some browsers (maybe just one), and not the others — this is a fantastic year to start figuring out how to ship it to all users on all browsers.
