By the instruction on David’s website and mark’s help I build firefox on my first try. But I wasn’t understand clearly about the steps of building it and why it worked that way, at least I didn’t figure out the problem by myself. So I format my hard drive and redo everything by memory and it worked again. All the steps are not too hard to follow, but the building took too long time. Now I am familiar with building firefox on windows.
