The short answer: no, there likely was not a change.<\/p>\n

One of the top sources for browser market share analysis recently released some interesting data<\/a> showing a decline in worldwide market share for Firefox during the March to April time period.<\/p>\n

Our internal numbers show healthy growth for Firefox usage during that time, and we found it a bit odd that both Opera and Safari also showed losses, while IE took a big step forward.\u00a0 Thankfully, we were able to dig into the numbers via Net Applications’ service; and even more helpful than that, the good folks over at Net Applications<\/a> sprung into action to see if they could dive even deeper into the data.<\/p>\n

What did we find?<\/p>\n

    \n
  1. Usage of Firefox did not appear to decline in April.<\/li>\n
  2. Usage of IE saw an ultra unusual spike over the period of a few days in April.\u00a0 While there was steady traffic from IE users \u2013 as measured by page views<\/em> \u2013 for a short period surrounding April 18th, there was a huge spike in traffic from IE users \u2013 as measure by unique visitors<\/em> \u2013 during the same time period.\u00a0 When I say \u201chuge spike\u201d, I mean something on order of 25% to 50% greater than what could have been expected.<\/li>\n
  3. Most of IE’s spike was attributable to IE6 users on XP (with some assistance from IE7 users on Vista), and nearly the entire spike came from users outside North America.<\/li>\n<\/ol>\n

    We’re not entirely sure what explains the IE related events described above, so we’re continuing to work with Net Applications in researching the situation.\u00a0 For example, one educated hypothesis is that it has something to do with Microsoft\u2019s update mechanism (they released SP1 for Vista users around April 18th).<\/p>\n

    There are likely to be more articles about the data (such as this<\/a>), so our goal here is just to be as open and transparent as possible.\u00a0 We\u2019ll keep you updated as we uncover more details.<\/p>\n","protected":false},"excerpt":{"rendered":"
