根据 Mozilla 官方网站上的编译步骤操作总会遇到各种各样的错误提示，以下是在虚拟机环境下验证通过的编译步骤。
1、准备工作
1) 依次安装 Visual C++ 6, Visual C++ Service Pack 5, Visual C++ Processor Pack。
2) 安装 cygwin 至 C 盘根目录，选择 DOS 风格（默认为 UNIX 风格）。除默认组件外，还应选择以下组件：
# ash -- UNIX-like command line interpreter shell
# autoconf -- Wrapper scripts for autoconf2.1 and autoconf2.5
# coreutils -- GNU core utilities (includes fileutils, sh-utils, and textutils)
# cvs -- Concurrent Version System
# diffutils -- file comparison utility
# findutils -- Utilities for finding files--find, xargs, locate, updatedb
# gawk -- pattern matching language (Devel category)
# gcc -- C compiler upgrade helper
# grep -- text search tool
# make -- dependency analyzer for software builds (Devel category)
# patchutils -- a small collection of programs that operate on patch files
# perl -- a scripting language used to control parts of the build (Interpreters category)
# sed -- a search and replace language
# unzip -- zip file extraction (Archive category)
# zip -- zip file creation (Archive category)
3) 下载并解压 firefox-1.0.7-source.tar.bz2 至 C 盘根目录，解压后生成 c:\mozilla 目录。
4) 下载并解压 Netscape's wintools，在 buildtools 目录编写以下 BAT 文件，运行后生成 moztools 目录：
-------------- moztools.bat --------------
set MOZ_TOOLS=c:\mozilla\moztools
md %MOZ_TOOLS%
cd windows
install.bat
------------------ end -------------------
5) 编写 .mozconfig 文件保存至 c:\mozilla 目录：
--------------- .mozconfig ---------------
. $topsrcdir/browser/config/mozconfig
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/ff
ac_add_options --enable-optimize
ac_add_options --disable-debug
ac_add_options --disable-tests
ac_add_options --enable-static
ac_add_options --disable-shared
ac_add_options --enable-official-branding
------------------ end -------------------
6) 编写 mozbuild.bat 文件保存至 c:\mozilla 目录：
-------------- mozbuild.bat --------------
@echo off
set MOZ_TOOLS=c:\mozilla\moztools
set PATH=%PATH%;"C:\Program Files\Microsoft Visual Studio\VC98\Bin";c:\cygwin\bin;%MOZ_TOOLS%\bin
call VCVARS32.BAT
c:\cygwin\bin\make.exe -f client.mk build
------------------ end -------------------
7) 重命名 cygwin\bin\link.exe
2、编译
启动 cygwin 后运行以下命令
Administrator@win2kpro ~
$ cd c:
Administrator@win2kpro /cygdrive/c
$ cd mozilla/
Administrator@win2kpro /cygdrive/c/mozilla
$ ./mozbuild.bat
以下为编译时的部分输出结果：
Setting environment for using Microsoft Visual C++ tools.

MOZ_PHOENIX=1
MOZ_OBJDIR=$(TOPSRCDIR)/ff
