/*\
|*| Parabola additions to vendor.js
|*|
|*| TODO: Go through this and figure out what's nescessary, remove
|*| most of it.  This is mostly cargo-cult BS.  For example, disabling
|*| all the EME stuff... that's already off because of `--disable-eme`
|*| in `.mozconfig`.  Some of these settings no longer exist.  Some of
|*| these settings don't do anything on GNU/Linux.
|*|
|*| However, they don't seem to be causing any of the critical issues.
