Add-ons hosted on the AMO generally need to have their source code uploaded in an extra (really annoying) manual step.

Issues brought up during review must be addressed using best efforts. If corrections have been requested, the new version should not contain unrelated changes, as this complicates the review process and can lead to further rejections.

During review, the add-on undergoes basic testing in addition to code review. To facilitate the functional testing, the add-on author must provide testing information and, if applicable, testing credentials required to use the add-on if an account is needed for any part of the add-on’s functionality.

You can now distribute your add-on. Note, however, that your add-on may still be subject to further review, if it is you’ll receive notification of the outcome of the review later.
