Add-ons Review Update – Week of 2011/03/16


  • These posts written every 2 weeks explain the current state of add-on reviews and other information relevant to add-on developers.
  • Nominations at the moment are being processed slower than usual. The new review system required hundreds of add-on developers to renominate their add-ons, which has placed a large workload on the editor team. Nominations are currently taking several weeks (~4) to review.
  • Most updates are being reviewed within 5 days.
  • Most preliminary reviews are being reviewed within 10 days.

The Review Queues

  • These stats are taken from the last queue report.
  • 53 new nominations that week. 239 nominations in the queue awaiting review.
  • 70 new updates that week. 78 updates in the queue awaiting review.
  • 70 new preliminary review submissions that week. 135 in the queue awaiting review.
  • 363 reviews performed by AMO Editors in March.

Firefox 4 Compatibility

Firefox 4 will be released very soon! RC1 is the current stable release and it should become 4.0 final very soon. AMO already supports 4.0.* as a valid maxVersion, and there are no major changes expected that affect add-on developers. If your add-on is already compatible, you should update your maxVersion to cover all future 4.0 releases. Most of the necessary documentation to upgrade your add-on for Firefox 4 is readily available:

Notes for Developers

  • If your add-on listing has been disabled, it could be related to the mass sandbox cleanup we performed recently. You can still get it enabled again if you contact us. There are instructions in your add-on page.
  • Add-on Performance at XUL School. This article is highly recommended to all developers. It explains a few methods to improve add-on performance, including how to easily measure startup times.
  • The AMO Editor Guide. This new page in the wiki is a comprehensive guide to the work performed by AMO Editors. It will serve as an introductory guide for new editors, and is a step forward in being as transparent as possible with our review process.
  • Useful Information for Add-on Authors. How to improve review times for your add-on, information about the review process, etc.
