Answer 2

It's a large, long lived project, so it's got far too many to list. Especially when you consider ancillary technologies - for example, the Elkhound parser combined with their JavaScript engine creates Dehydra, used to perform static analysis and transform source code, used to bring the old XPCOM stuff up to more recent standards and update dependencies on JavaScript calls.

At the broadest level, the runtime consists of mostly C++ components, configured by XUL interface description language and scripted with JavaScript. IIRC, some of the JS engine code from Adobe is C rather than C++, as are some of the lower level networking libraries. Over recent years, some UI functions have moved from C++ into JS. Then there are the build support and debugging code, which can be Python, perl, make scripts, and so on.
