I'd like to know how much of an impact that had, but nonetheless Chrome is technically in many areas the best browser today and Mozilla, being the clear market leader at one point, could have done a lot more to prevent that. Firefox was in need of technical improvements for some time, but they only started acting when Chrome already had a noticeable market share and that's not how you stay at the top.
