AMO is open source

People are often surprised to learn that the software powering is completely open source and available for anyone to use and hack on. For example, Sugar Labs powers its Activities site with our code and even contributes improvements and fixes back to us.

But we’d really like more people to be involved. We know that people care about the quality of AMO because of the large numbers of bug reports, suggestions, and feedback we receive with every change.

If you’re interested in learning more about AMO development, take a look at our documentation on setting up an instance and join us in #amo on if you have any questions. We have plenty of bugs, and if there’s anything we can do to help you or other contributors get started, please let us know.

Fixing website bugs is one of the easiest ways to get involved with the Mozilla project, and a great way to improve the add-ons experience for the millions of users who visit our site every day.

    Under which license is the AMO source available? Where can I find the license mentioned in the source?

    I installed it on my dedicated server without issues. This is a very powerful CMS and we can even distribute it provided we strip it off the config files and settings. I’d like to work on it and make this possible. I had been testing Drupal for similar functionality but to no avail. And the closest I got to a CMS meant for hosting software was the AMO source. If I can find more documentation I can bundle it so that we can even distribute this as a Mozilla project.

    PS – I know this is not a support forum but I couldn’t manage to publish a test addon and downloading the already existing addon resulted in “Add-on not found!” message. Is there a place we can search for resolutions of the same?
