November 9th 2009 is Firefox’s fifth birthday. Firefox and WordPress have grown up next to each other so we’ve always felt a brethren spirit with their team as we work toward the same goal, making the web a better place, from opposite ends of the spectrum.

Just out of curiosity, I wondered how Firefox was doing in our browser stats compared to the posts I did in 2008 and 2007.

1. Firefox — 45.7%
2. Internet Explorer — 38.7%
3. Safari — 8.75%
4. Chrome — 5.2%

This is the first time I’ve ever seen Firefox pass IE in market share for a mainstream audience like WordPress.com has.

As you can see, competition in the browser market is still alive and well. Of everything available, Firefox still continues to be my primary browser for every day usage. (And Thunderbird for my email.)

Take a few minutes and wish them a happy birthday.
