Add-ons Update – Week of 2014/10/01

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 7 weeks to review.
  • 124 nominations in the queue awaiting review.
  • Most updates are being reviewed within 6 weeks.
  • 88 updates in the queue awaiting review.
  • Most preliminary reviews are being reviewed within 6 weeks.
  • 147 preliminary review submissions in the queue awaiting review.

The Add-ons Team met last week to discuss various issues related to the add-ons world, including the time it takes to perform a review and what we can do to improve it. I’ll be posting a summary about everything we discussed shortly.

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 32 Compatibility

The Firefox 32 compatibility blog post is up. The automatic compatibility validation was run shortly thereafter.

Firefox 33 Compatibility

The Firefox 33 compatibility blog post is coming up, probably tomorrow. Expect the automatic compatibility validation to be run sometime next week.

As always, we recommend that you test your add-ons on Beta and 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. We will also begin contacting developers about add-ons malfunctioning with e10s very soon. For now we recommend you start looking at the available documentation.

    You still haven’t reviewed adguard! Addons not reviewed by Mozilla won’t auto-update? Fair enough. Good defense against pesky adware/hijacker extensions! I tried manually updating (clicking Check for updates) but Firefox says no update for adguard. To update, I have to remove old version then install the new one from scratch! Btw, if extension’s auto update is set to off, clicking Check for updates (drop down) should not update said extension.

      All you need to do is download the unreviewed version from the All Versions page and install it. No need to remove the old one.

    Or maybe if extension’s auto update is set to off, Firefox will not auto download and install the update when you click Check for updates. Instead, in the extensions list an update button, latest version number and date of release will appear beside the extension’s name.

    When will Firefox 33 stable apk be available on Mozilla ftp? What’s up with the delay? I don’t use the Play store. I get the apk directly from dev’s site.

    Hello Jorge,
    My addon, addresslabel@markus, awaits full review for over 10 weeks and it has not moved closer than 20 on the queue.

    Could you please have a look?

    Best regards,

      Hello Jorge,
      I appreciate the review of version 6.
      I am very impressed that version 7 (a minor update) was reviewed in …. less than an hour!
      Very nice 🙂
