"Five years ago today, Mozilla announced the official release of Firefox 1.0. The open source Web browser has come a very long way since then and has achieved a level of popularity that few would have imagined possible. The success of Firefox and Mozilla's unwavering commitment to open Web standards has helped to usher in a new era of vibrance and diversity in the browser market. To commemorate Firefox's fifth anniversary, we are going to take you back in time for a look at some of our classic coverage of the popular browser."
I can't believe I've been using Firefox for ONLY 5 years. I feel like I've been using it forever. I adopted it because of security concerns and because I wanted to try tabbed browsing. I really can't remember when I last used IE except for things like some Microsoft sites. Occasionally, I still find a site that doesn't render well in Firefox, but that has become extremely rare as time goes on.
