By examining the data and addressing a number of research questions, two very different profiles emerge: Firefox, as the older and established system, with long product version cycles but short bug fix cycles, and a user base that is slow to adopt newer versions; and Chrome, as the new and fast evolving system, with short version cycles, longer bug fix cycles, and a user base that very quickly adopts new versions as they become available (due largely to Chrome's mandatory automatic updates). %B Proceedings of the 8th working conference on Mining software repositories - MSR '11 %I ACM Press %C New York, New York, USA %P 238-241 %8 05/2011 %@ 9781450305747 %!
