Firefox's growth at Internet Explorer's expense has been halted and now reversed, with large numbers of users defecting from both Microsoft's and Mozilla's browsers.

Do we have actual numbers showing this? I'm honestly curious. For IE, the decline is so fast that clearly users must be leaving in large numbers, but Firefox has been losing market share very slowly, slower than the web is growing. My best guess is that Firefox is growing in absolute number of users, while losing market share because the competition is taking most of the growth. Does anyone measure user "churn", that is, not just number of users, but how many users were gained and lost (in other words, gaining 10 users looks the same as gaining 30 and losing 20, if you just look at the total usage numbers).
