I post these updates every 3 weeks to inform add-on developers about the status of the review queues, add-on compatibility, and other happenings in the add-ons world.

The Review Queues

In the past 3 weeks, 1228 listed add-on submissions were reviewed:

You can read about the improvements we’ve made in the review queues here.

Compatibility

The compatibility blog post for Firefox 49 is up, and the bulk validation was run. The blog post for Firefox 50 should come up in a couple of weeks.

Going back to the recently released Firefox 48, there are a couple of changes that are worth a reminder: (1) release and beta builds no longer have a preference to deactivate signing enforcement, and (2) multiprocess Firefox is now enabled for users without add-ons, and add-ons will be gradually phased in, so make sure you’ve tested your add-on and either use WebExtensions or set the multiprocess compatible flag in your add-on manifest.

As always, we recommend that you test your add-ons on Beta and Firefox Developer Edition to make sure that they continue to work correctly. End users can install the Add-on Compatibility Reporter to identify and report any add-ons that aren’t working anymore.

Extension Signing

The wiki page on Extension Signing has information about obtaining the unbranded builds to test on release and beta. We will try to make them easier to get to, but for the most part the Firefox 48 release marks the end of deploying this change, after years of work.

Recognition

We would like to thank these people for their recent contributions to the add-ons world: Rob Wu, NilkasG, and h4ever.
