Add-ons Update – Week of 2015/03/18

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 8 weeks to review.
  • 153 nominations in the queue awaiting review.
  • Most updates are being reviewed within 4 weeks.
  • 61 updates in the queue awaiting review.
  • Most preliminary reviews are being reviewed within 6 weeks.
  • 161 preliminary review submissions in the queue awaiting review.

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 37 Compatibility

The Firefox 37 compatibility blog post is up. The automatic AMO validation will be run this week.

Also, if you host your add-ons outside of AMO, give this update a look. It affects the way the domain whitelist for add-on installation works.

Firefox 38 Compatibility

The Firefox 38 compatibility blog post was published yesterday. The automatic AMO validation will be run next month.

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.

Extension Signing

We recently announced that we will require extensions to be signed in order for them to continue to work in release and beta versions of Firefox. If you’re an extension developer, please read the post and participate in the discussions. We will be posting a followup shortly, expanding on the reasons behind this initiative.


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 future. For now we recommend you start looking at the available documentation.

    Firefox wants to update and I won’t let it because it keeps blocking my Kaspersky anti virsus extension.
    I like Kaspersky and it does a great job keeping my computer safe. What can I do to stop firefox from blocking it?

      You’re probably running into compatibility problems, which tends to happen if Firefox updates before the antivirus software updates. It’s always recommended that you use the latest versions of both. However, if this is a recurring problem, it’s probably best if you hold off on updating Firefox for a week or so to give Kaspersky time to update and avoid the conflict.
