Hi

I'm new to mozilla development. I would like to know what classes and
methods are defined by the mozilla libraries, I've been having a look at the
source code, but it's turning out to be rather tedious. Is there a simple
list anywhere?

I also can't seem to find certain files. For example, some of the source
files have #include "nsIInputStream.h". However, I can't find this header
file and I've just downloaded all the source code. Is there something I
should know?

Cheers
