No, many of the firefox deps can be treated as "a recent version
of", but if you go too far back the initial configure process will
fail (followed by weird error messages :)
However, for rustc we only update the book when we have to, and then
we (now) use the current release - assuming it is ok. On one
occasion I dropped back a version, but it turned out that building
rustc using python3 was the problem (builds, but from time to time
seems to return error status when building firefox).
For ff60, ISTR nss-3.36.1 is a minimum.

No. It can't have its own version of glibc. It does ship with its
own copy of llvm - I've had a report that using system llvm even
when newer has worked in the past. Using older system llvm, of
course, is unlikely to work.
