I’d like to learn how FireFox works behind the scenes. I’d like to understand the source code and the different components but the code-base is rather large and I’m not sure where to start.
I’m wondering if there is some sort of walk though written up by anybody either from the firefox team or from outside the community.
I’ve looked a little bit at: https://developer.mozilla.org/En but I don’t see anything that screams ‘Start here’. I’m simply trying to review their code base for [self-]educational reasons.
Seneca College in Toronto has a program geared towards exactly this — beginners to Mozilla development.
Check out some of these links:

If you need any help, use IRC: #seneca on irc.mozilla.org. Don’t worry if you’re not a (Seneca) student, lots of people around the world (people from Seneca, people from Mozilla, and others) are in this channel, the purpose is to educate developers about open source in general and the Mozilla project specifically.
Good luck!
