Firstly: this question would be better-addressed to the "firefox-dev" list: https://wiki.mozilla.org/Firefox/firefox-dev This list here (dev.tech.layout) is for discussion of the internals of Firefox's layout engine. (not about Firefox frontend/JS code)
But, I'll give a brief answer -- yes, many Firefox JS & CSS & HTML files are run through a preprocessor, *during the Firefox build process*. You can "compile" that code (have it preprocessed) by compiling Firefox -- for help with that, see: https://developer.mozilla.org/en-US/docs/Simple_Firefox_build If you have further questions on these preprocessor directives in Firefox JS files, please direct them to the firefox-dev list (linked above), rather than to dev.tech.layout.
