Indeed, it looks like the newer versions of these packages are missing
from older Ubuntu releases, making it impossible to rebuild Firefox from
scratch.

I'm currently unable to compile the firefox package in Ubuntu 16.04 and
17.10 because the available versions of cargo and rustc are too old:
$ sudo apt build-dep firefox

** Description changed:
Firefox 56+ will require rust 1.17 and cargo 0.18 to build.
The beta-phase for Firefox 56.0 begins on 7th August and release
candidates will be available from 18th September.
17.10/Artful still requires an update of cargo first while rustc is
sufficient
