How can I download my signed addon from the Developer Hub?

This was copied form another recent reply of mine.

You can find links to an add-on’s XPI files a couple of different ways:

  1. (Listed) From the public listing.
    1. Open the public listing for the add-on on AMO.
    2. Follow the “See all versions” link in the “More information” section of the page.
    3. The main content of this page is the version history list. Each entry will have a link to an .xpi file in the bottom right corner.
  2. (Listed and unlisted) In the Developer Hub.
    1. Open the Manage my Submissions page.
    2. In the add-on list, follow the link to the desired add-on.
    3. Follow the link titled “Manage Status & Versions”.
    4. In the version list, follow the link to version you wish to download.
    5. If the version was approved, you should see a link to an .xpi file in the “Files” section of this page.
