>From what I can tell the maintainers have no intention of spending time
supporting Ubuntu 16.04 or older. Even when Xenial was the current LTS
they weren't responding here, and now that 18.04 has been out for 5
month there's even less motivation to handle older distros.

Having built Firefox 59 from source I think I get some of the reasons
why they'd consider this a heavy support task. It's hard to get gcc and
Rust to play nice on old cross-compiling toolchains, not to mention that
sketchy assembly code for XPCOM. From a practical perspective, user
workarounds can go in this order:

1) Use the latest firefox:armhf on 18.04 Bionic, if that's what you're
running or you're open to upgrading.

2) Earlier distros like 16.04 or Debian Stretch: Install the latest
firefox:arm64 if your system supports AArch64.

3) If armhf is the only option and you're on 16.04, you can still set up
the firefox 18.04 deb package from Launchpad. Download its dependencies
like libstdc++ and following my instructions in #117 to place the
appropriate runtime-linked libraries.

Relying on armhf builds from Bionic in the worst case 3): this avoids
having someone to maintain the whole build flow for Xenial and Trusty.

I'm only speaking for Firefox here, but if it all comes down to crashes
in libxul.so then maybe much of this is sufficient for Thunderbird too.
