What is the Mozilla Developer Network?

The Mozilla Developer Network (MDN) supports the growth and development of Firefox and the web by providing comprehensive, accurate, and up-to-date documentation and news about Firefox, Mozilla, and web development technologies.

Our primary audiences are:

  • Web developers -- People who create the myriad sites and content for the web.
  • Firefox extension and XUL application developers
  • Mozilla contributors -- The "loose band of freewheeling computer programmers from around the world" who create the Mozilla technologies at the foundation of all of this.

MDN? What about MDC?

MDC (Mozilla Developer Center) was originally just a documentation wiki. When additional community features were added (Demo Studio, Learning pages), the name was changed to Mozilla Developer Network. The name "MDC" lives on as "MDN Documentation Center" — the documentation wiki part of MDN.

What is the future of the Mozilla Developer Network?

The Mozilla Developer Network is positioned to take a leadership role in providing a valuable and community-driven resource for web development. We've build the foundation now for a comprehensive, usable, accurate, and valuable resource that developers will use on a daily basis.

If you have any ideas about what this project could become (or how to get there), please come join the fun.

As part of that growth, we are working on a new platform for site, based on the same codebase as the SUMO end-user site, but with additional features to meet the needs of a developer audience. See Project Kuma for more information.

I've found a bug on the site, what do I do about it?

If you have found a problem with anything related to this site (website, stylesheet, documentation, processes, etc.) that you aren't able to fix yourself, please send a note to our mailing list, or file a bug against MDN.

How do I monitor pages for changes?

There are three ways you can watch for changes to pages, all of which involve RSS feeds. To access the feeds, choose the "RSS feeds" option in the "Site tools" drop-down menu at the top of the page. This will present you with a list of RSS feeds you can subscribe to.

If you want to be notified every time any page on the site is edited, you can subscribe to the "What's new?" feed. If you only want to be notified when specific pages that interest you are edited, subscribe to the "My watchlist" feed. You can also subscribe to feeds to watch changes made by specific users.

Once you're watching your watchlist feed, you need to add articles to your watchlist. To do this, navigate to an article and choose the "Watch this page" option from the "More options" drop-down menu immediately below the site's heading banner. After that, you will receive notifications in your RSS feed reader when that page is changed.
