Re: Compile firefox JavaScript code

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. Thanks!
