Today I tried my luck compiling a custom XPCOM Component for XULRunner. The component wouldn't load, simply leaving an error in the console "Failed to load XPCOM component: ...."

I was having a terrible time debugging the problem and I couldn't seem to find the relevant documentation. Finally I asked for help on the #mozpad irc chat room. Plasticmillion pointed me to the correct document that I couldn't seem to find on google for whatever reason.
