The Mozilla Foundation, as I am sure you know, rolled out the final version of Firefox 4 to the masses last week. Turns out that the launch of Firefox 4 was a big hit – even bigger than the launch of Microsoft’s Internet Explorer 9 (IE9) web browser.

Microsoft announced that the final version of its IE9 browser was downloaded 2.35 million times in the first 24 hours after its release. Ryan Gavin, Senior Director, Internet Explorer Business and Marketing put things in perspective by saying that 2.35 million downloads in 24 hours is the equivalent of over 27 downloads every second, or over 240 downloads every 9 seconds.

Mozilla made public some details about how successful the launch of Firefox 4 was and it seems it has Microsoft beat. In the first 24 hours after the launch of Firefox 4, it was downloaded 7.1 million times (and that’s on top of the 3 million Firefox 4 RC users). In the first 48 hours after the launch of Firefox 4, it was downloaded 15.85 million times. Mozilla explained that the 15.85 million downloads are the equivalent of 33 round trips to the moon, if each download were a mile.

Those aren’t the only statistics Mozilla made public. It made public these other statistics as well:
- At peak times there were 10,200 Firefox downloads per minute.
- On average, there were 5,503 Firefox 4 downloads in the first 48 hours.
- There were 91.7 Firefox 4 downloads per second in the first 48 hours.
- In all, Firefox 4 downloaders downloaded 193.4 million megabytes.

The United States was the top country to download the final version of Firefox 4. According to Mozilla, 4.45 million US downloads of Firefox 4 were recorded. The top region to download Firefox 4 was Europe. Mozilla explained that 6.63 million Europe downloads of Firefox 4 were downloaded in the first 48 hours.

Mozilla CEO Garry Kovacs said Firefox 4 is “blazingly fast” and “cleverly intuitive to use.” “Beyond the obvious, Firefox 4 more profoundly starts the redefinition of the “browser” – from a piece of code traditionally used to simply view, and link to static information, to a trusted environment we live our online lives in, and which we rely on to securely engage with information, applications, friends, colleagues and so much more,” Kovacs added.
