Yes, and no. Firefox is actually bigger than it used to be when Chrome launched. It was at around 20-24% back then. But yes, Chrome did steal market share from Firefox. I think by now it got most of the early adopters and devs from Firefox. But in the same time they both kept eroding IE's market share, so overall Firefox grew by getting some IE users, and losing a few to Chrome, while Chrome grew from both IE and Firefox. I think it's a pretty win-win situation for both, at least for now. Together they are big enough to standardize some features, even without Microsoft's support (like say WebM, WebGL, or Native Client). So, I think that's good. On a side note, I think something like 40-50% of Techcrunch readers are using Chrome, and that's a pretty good indication to where Chrome is going, just like it used to be for Firefox, when it had only 10-15% overall marketshare, but around 25-30% on tech sites. And now has caught up to that.
