Add-ons Update – Week of 2015/02/04

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

  • Most nominations for full review are taking less than 6 weeks to review.
  • 46 nominations in the queue awaiting review.
  • Most updates are being reviewed within 2 weeks.
  • 22 updates in the queue awaiting review.
  • Most preliminary reviews are being reviewed within 6 weeks.
  • 44 preliminary review submissions in the queue awaiting review.

Thanks to our volunteer reviewers, most new submissions are being handled within a day or so (the measurements above are based on the state of the queue and not the actual waiting times). We still have a large backlog of complex add-ons that require admin review, but we’re making progress in decreasing it.

If you’re an add-on developer and would like to see add-ons reviewed faster, please consider joining us. Add-on reviewers get invited to Mozilla events and earn cool gear with their work. Visit our wiki page for more information.

Firefox 36 Compatibility

The Firefox 36 compatibility blog post is up. The automatic AMO validation will be run next week.

As always, we recommend that you test your add-ons on Beta and Firefox Developer Edition (formerly known as Aurora) 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.


Electrolysis, also known as e10s, is the next major compatibility change coming to Firefox. In a nutshell, Firefox will run on multiple processes now, running each content tab in a different one. This should improve responsiveness and overall stability, but it also means many add-ons will need to be updated to support this.

We will be talking more about these changes in this blog in the near future. For now we recommend you start looking at the available documentation. If you want to help us test add-ons on e10s, please visit

    Thanks for the update. It’s a little frustrating that bug 1103442 has been so persistent these past few months. At this point, the active daily users metric often seems unreliable even when it does appear.

    Who reviews existing Add-Ons?
    An adware problem has cropped up with Flash Video Downloader – namely it’s latest update contains unwanted adware in the form of a slide header showing chix in bikinis. (I know, how much of a problem can that really be for most of us guys, right? LMFAO – but it’s really annoying.)

      We’ll look into it, thanks.
