The Review Queues

In the past month, our team reviewed 2,490 listed add-on submissions:

  • 2,074 in fewer than 5 days (83%).
  • 89 between 5 and 10 days (4%).
  • 327 after more than 10 days (13%).

244 listed add-ons are awaiting review.

Compatibility Update

We published the blog post for 56 and the bulk validation has been run. This is the last one of these we’ll do, since compatibility is a much smaller problem with the WebExtensions API.

Firefox 57 is now on the Nightly channel and will soon hit Beta, only accepting WebExtension add-ons by default. Here are some changes we’re implementing on AMO to ease the transition to 57.

    Hey! I was wondering if there’s a triage done before the review occures? Because I keep reading that 80-85% of the reviews take less than 5 days, but mine are consistently taking around 10 days. And I’m wondering if there’s something that explains this (and if I have any means to prepare my addon submission so that review time is lower), or if it’s just bad luck. Thanks for your awesome job anyway guys, and if you have any more information for me… 🙂

      There are a few factors involved. New submissions can take longer than updates. Code complexity, heavy use of libraries, using minified or obfuscated code can also delay reviews. Volunteer reviewers can pick anything from the review queues, so certain kinds of add-ons will be reviewed more quickly than others.

        Thanks for your answer Jorge! Well I think this might be related to the way I deliver my code. I’ll try to do differently next time, thanks a lot for this insight 🙂

    I just tried to develop a WebExtension with native script modules, but it doesn’t seem to work.
    I also enabled the “dom.moduleScripts.enabled” flag.

    Maybe Firefox is experiencing the same bug as Chrome?

    I couldn’t find a matching issue in the Firefox bug tracker…

      I think this bug answers your question:
