Add-on content reviewers help ensure that extensions listed on (AMO) adhere to Mozilla’s Acceptable Use Policy.

Guidelines for Content Review

Mozilla’s Acceptable Use Policy lists criteria for unacceptable content, and these criteria also apply to AMO. Some examples of unacceptable content under this policy that might be found in extension listings include:

  • obscene or pornographic images
  • hate speech (note: anything that promotes Nazism or uses Nazi symbols must be rejected)
  • advertisements for illegal products or services

Add-on content reviews should also adhere to these additional guidelines:

Spam Add-ons that are clearly spam should be rejected. Some indicators of spam include: Large content block of SEO search terms Links to websites that are unrelated to the Firefox extension

Copyright or Trademark Violations With the exception of Mozilla trademarks, reviewers do not handle reports of copyright or trademark infringements. Determining copyright or trademark infringement is a complicated legal process that should be handled by Mozilla’s legal team. For these issues, reviewers should follow the DMCA process and direct copyright or trademark holders to contact the Mozilla legal team.

For Mozilla trademarks, the usage of “Mozilla” and “Firefox” are generally not allowed in the add-on name, except in the following format: “ADD-ON NAME for Firefox.”

Sexual Content Any child pornography must be escalated to Mozilla for reporting to the National Center for Missing and Exploited Children (NCMEC). Please send an email to and include the following:

  • Extension ID number
  • Link to the author’s profile
  • Short description of the image
  • Date and time the extension was submitted

Review Process

1. Log in to

2. Select the Content Review queue. This will list include all submitted extensions that need a content review.

3. Click on an add-on in the queue to start reviewing its content.

4. Check to make sure the extension listing clearly describes what the extension does, and would be understandable to users who do not have domain knowledge of the service the add-on is working with. The following fields must be filled out:

  • Title
  • Summary
  • Description (only if the summary doesn’t say it all)

If an extension looks unobjectionable (i.e., not spam) and does not have a description, use the reviewer tool to request information from the developer and ask them to include a description.

5. Check the following information to make sure it adheres to the Acceptable Use Policy:

  • Title
  • Icon
  • Description
  • Screenshot content

Note: if you see that an author’s name violates the Acceptable Use Policy, please escalate to an admin.

6. If the extension complies with the policy, click “Approve.” You can move on to the next extension.

  • If the extension does not adhere to the policy, click “Reject.” Select all versions and enter the rejection message in the box.
  • Rejecting an extension will send a message to the developer and remove the extension’s listing on (AMO).


If you are not sure about whether something is acceptable or not, escalate it to a staff reviewer. Don’t reject immediately.

You can contact staff reviewers on IRC in the channel #addon-reviewers or by clicking ‘Request Super Review’ in the review tools.
