After my first experience building Firefox, I must say I learned a lot. One reason was because I built it with Linux linux which is an operating system I'm least familiar with. Another reason is is that I found another great source for information which is IRC chats. I'm glad open source developers use IRC. If everything ran by emails, I would have ran out of patience in building Firefox.

One suggestion I would make is, [http://developer.mozilla.org MDC] should have forums so people can post their issues and how it was resolved. One of the issues I ran into was missing libraries which was not listed on the prerequisites. Although Mozilla's instructions were meant more for developers, it should describe in details of the steps in order for the users to build the source without having issues. Reading the instructions provided require quite a lot of troubleshooting.
