Given our focus on skills development and outreach for open source, it's no surprise that 65% of browsers coming to FOSSLC are Firefox. (though it would be nice to see a few more IE users sniffing at our site as they're who we're trying to help!)

W3Schools make their browser statistics available. It shows that Firefox leads with 46.4% of the market and growing. No doubt this population is skewed towards developers.

The data we've seen shows Firefox use at just over 20% for the general population of Internet users.

So here's a thought - are developers innovators/early adopters and thus we can expect to see a rise in Firefox use? I would expect so based on the assumption that developers are technology-savvier than the general population and are changing browsers for a reason. This will be interesting to follow over time.
