FireFox is subject to the same engineering problems as IE. I would expect the defect rates to be practically the same. If you've studied software engineering, you know this to be true. There's nothing magical about FireFox developers or their methodology. In the end, their defect rate per KLOC will be no better or worse than IE's.

BTW, you do realize that FireFox incorporates the work of numerous other projects (ie. Gecko, etc), right? So, in fact, the number of developers, testers, designers, and other folks working on the code that FireFox needs to execute is actually far greater than you've specified. I'm letting that slide for the moment because you've consistently failed to identify how many developers et al are working on IE. I'm still waiting for a response.
