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.

    Die Werteilung ist sehr interessant. Nimmt man den Datenschutz mal beiseite, spiegeln die Nennungen in manchen Ländern vermutlich auch die grundsätzlichen globalen Bedürfnisse wider. Schöner Einfall, Daumen hoch!

    I’m a big fan of Google.
    Apart from that, I was curious how the counter for those people who are using Firefox is increasing at almost a fixed rate of 666 increments per 7-8 seconds?!
    Anyways, great Job with the update..

    I was just watching the video when something of amazing has happened:
    Thousands of enlightened points have appeared on the screen bringing with them the meaning of freedom.
    You’ve gave us the access to a powerful tool for staying tuned with the rest of the world and we’ll do our best to keep it alive by using it day after day!
    Keep your wonderful work up, guys.

    I’ve been a staunch Firefox and Thunderbird fan and user since Netscape’s early days. I like what Mozilla stands for and believe in the principles that drive the foundation forward. I hope it continues for a long long time to come.

    This “web you want” campaign leaves a bad taste in my mouth. Its propaganda. For a good cause, but still propaganda. You’re not asking people what they want. You’re presenting a preselected list of make-me-feel-good memes and inviting them to click. Of course we’re going to click. But what does a click mean? Is that counted as a vote? What if I wanted to rank the selections? Or just wanted to read more about them, to understand more deeply? What about things which aren’t on the list? What if I actually disagree with one or more of them?

    This campaign is straight up manipulation, attempting to create/fuel/extend a movement. You’re doing it on purpose, and it stinks.

    Keep to what is good and true. Leave the social manipulation exercises to those who have something to conceal.

    Mozilla Firefox is my choice for many years. And I like that the Community is connecting with the users, and I hope that they will do that once a month or so. And I want to thank every developer for making Mozilla Firefox.

    I agree with those who’d like to select more than one priority choices. Several are critical to one another’s function. Learning is key, for instance, but not widely possible without accessibility. Thank you Thank you for being Mozilla!
