Add-ons Update – Week of 2016/07/13

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, 1278 listed add-ons were reviewed:

  • 1194 (93%) were reviewed in fewer than 5 days.
  • 62 (5%) were reviewed between 5 and 10 days.
  • 22 (2%) were reviewed after more than 10 days.

There are 74 listed add-ons awaiting review.

You can read about the recent improvements in the review queues here.

If you’re an add-on developer and are looking for contribution opportunities, please consider joining us. Add-on reviewers are critical for our success, and can earn cool gear for their work. Visit our wiki page for more information.


The compatibility blog post for Firefox 48 is up, and the bulk validation was run. The post for Firefox 49 is also up and the bulk validation will be run in the coming weeks.

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 the timeline, as well as responses to some frequently asked questions. The current plan is to remove the signing override preference in Firefox 48. The unbranded builds, which were the final piece, are available here. We will update the Extension Signing doc with more information about how to obtain them.


We would like to thank these people for their recent contributions to the add-ons world: Sylwia Ornatowska, dw-dev, Lavish Aggarwal, Baris Derin, Martin Giger, Viswaprasath, gorf4673, and Atique Ahmed Ziad.

You can read more about their contributions in our recognition page.

    I don’t see where we can download the unbranded builds when I follow the “available here” link –

      On that page you should see a list of platforms, with a green B next to them. The B opens a panel at the bottom, where you should click on the link next to “Build”, which takes you to the directory where you can download the build.

      I know it’s convoluted, but we’ll work on making this easier.

      If your Firefox is slow, I suggest disabling add-ons to see if any of them are the cause. If you find a specific add-on that slows down those websites, it’s best to contact the developer about it. Most add-ons have support information listed that you can use to get in touch with them.
