Celebrating the Web We Want


The latest version of Firefox is a huge milestone for Mozilla and represents the combined efforts of hundreds of people from around the world. To celebrate this launch we revisited Glow, a real-time visualization of Firefox downloads originally used during the launch of Firefox 4 in 2011.

This time we wanted to do more than just show downloads. We wanted to give people a chance to express what they want the Web to be. To this end, users visiting https://webwewant.mozilla.org/ have the option to share with Mozilla and the world their hopes for the Web. These “shares” are displayed on the map and we display information about which issues are most important in each continent and country.


The dots on the map represents people: either someone downloading Firefox or sharing the Web they want. For me, watching the map is both humbling and inspiring. When people use Firefox— a free and open source browser made by an amazing community— and choose to share with the world what matters to them, it shows a global commitment to the future of the Web.

Technical Details

How do we process millions of interactions and display them?

The site processes request logs for Firefox downloads, auto-updates, and users who share via the website. We perform geolocation lookups on the data and aggregate the information for consumption and display by the Web application.

We have a particular love of the Simpsons on our team and elements of our project are named appropriately:

  • Mr. Burns – The overall codebase.
  • Smithers – The “servant” scripts who provide data to Mr. Burns.

Mr. Burns relies on three main scripts to display data:

  • Bart – Parses log files looking for Firefox downloads or auto-updates.
  • Lisa – Geolocates parsed data and aggregates into buckets.
  • Milhouse – Packages data into JSON for consumption by the front-end.

The flow of data can be seen in this diagram:


Data is stored in Redis and the JSON files are delivered to the front end application via CDN. The front end app renders the individual “glows” and the stats using D3.js.

    Why are you people doing this? Why you keep updating the browser every now and then. The new versions are not supporting the existing addons. Please resolve this issue asap. I get messages that the java script are stopped. I am really disappointed with Mozilla browser

    I’m afraid that not all of us share your self congratulations about this new V29, its awful!
    Its implementation has been disastrous.
    You people are clearly happily enjoying your programming expertise and skills, BUT you seem to have forgotten the poor ordinary every day user who needs precise help and clear guidance.
    Documentation and help on FIREFOX 29 is almost none existent.
    That dreadful BLUE SCREEN OF DEATH (Mozzila Version= CAMPAIN) is terrible. No matter how many times we try to get rid of it by completing it, it just keeps coming back and waste’s time and is very annoying.
    Do any of you remember the BETAMAX system? The best VCR system by far, but doomed because it wasn’t developed for the users.
    I’m very sorry, but you are doing the same thing to Firefox with v 29.

    Design yang baru dan menarik, serta user friendly. Tetapi masih lagi berat macam dahulu. Mungkin yang itu sahaja fokus untuk dibaiki.

    Sekian terima kasih.

    If you truly value freedom on the web, you would have stood behind your CEO. He has a right to his views. Until you canned him, I was a user of Firefox. Now I am stuck with Safari.

    Dear Firefox,
    As Web experience now take place more and more on different type of machine, I would like that data implied be synchronized on all of mine. Peer to Peer mechanism seems a candidate of choice for silent technology. I am looking for it’s implementation to sync Browser files. I will appreciate to have it available also for my own files stored in a designated folder. By letting let say my home computer switch on I will appreciate to also be able to navigate through it from my mobile or my office computer.

    Achievement of individual is a goal or may be a goal to have name and fame but all achievement is worthless for others because it do not effect on other’s.Presently every organisation is meant to gene rate huge profits.As of my knowledge Firefox is dedicated to unkno wn person’s effecting their lives.My thought makes Firefox more tr usty & reliable because I and many of us are not individuals but a f irefox community all around the globe.

    Mozilla, you say: for everyone, freedom, possibilities, privacy, learning, control. I think it’s nice and right. But than I say CEO. And I am sad. And I know – Firefox is not my choice.

    Been using Netscape/firefox for a long time. It’s a browser that I can setup the way I want. A browser that I can decide what search engines to use. A browser that I can decide what add-ons to use. A browser that I can decide what my home pages are.
    I do not like it when programs try to change my add-ons or search engines. They are tricky the way they try to take over. Thanks firefox for finding a way to prevent them from taking over, and a way of getting rid of them if they do.
    Keep it simple – great motto!

    The United States federal agency, NSA (National Security Agency) is spying on American citizens through the internet. This violates basic rights provided to American citizens by the U.S. Constitution, which is the Law of the Land in America. I support a private, user controlled internet. That’s why I use Firefox.

    I Love and Hate Mozzila.
    I Love it because Mozzila have good styles, and open source.
    I Hate it, because Mozzila is “eat” the most, of my RAM, and it’s too heavy.
