Firefox market share passed 10%. That doesn’t seem like much, but it’s a near doubling in the last 18 months. Some weird variation of Moore’s Law here? 🙂

The question is when Firefox becomes a problem for MS. I think it already is. The issue isn’t total share but who’s got da buzz. The Firefox users I know are computing enthusiasts who’ve taken the time and trouble to download, install and learn how to use a new browser when IE was sitting right their on their desktop. Firefox’s barrier to entry is really quite high, which makes the 10% penetration all the more notable. I’d also presume that those 10% are the kind of demographic Microsoft would really like to have.

On the other hand, since the “stable” 1.5 release of Firefox came out, I’ve experienced more freezes, crashes and weird behavior in Firefox than in Internet Explorer. Maybe success = feature creep = bloatware. It happened with IE.
