Add-ons Review Update – Week of 2011/03/01


  • 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 a week or two to review.
  • Most updates are being reviewed within 5 days.
  • Most preliminary reviews are being reviewed within 5 days.

The Review Queues

  • These stats are taken from the last queue report. Preliminary queue stats are still pending.
  • 59 new nominations that week. 161 nominations in the queue awaiting review.
  • 80 new updates that week. 50 updates in the queue awaiting review.
  • 2620 reviews were performed by AMO Editors in February (updated March 1st).

Firefox 4 Compatibility

Firefox 4 will be released very soon! Beta 12 is the current stable release and the first Release Candidate (and hopefully the final 4.0 release) should follow 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 was recently disabled, it could be related to the mass sandbox cleanup we performed recently. You can still get your listing enabled again if you contact us. Your add-on page should have instructions on how to contact us.
  • 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.

    You should fix the bugs on AMO that appear with latest nightly:

    Error: uncaught exception: TypeError: window.wrappedJSObject.navigator.__defineGetter__ is not a function

    Error: VersionCompare is not a constructor
    Source File:
    Line: 10

    And theme compatibility is not showing because of it.
