According to the website, version 52.9 is the last "supported" version
(and is what I am using now). But that version does have some issues on
some sites (esp with regards to videos, which need more HTML5 (and mp4)
capability, than is provided by FF version 52.9). (case in point - try
to watch some videos on ted.com without having to fall back to a
somewhat jerky flash version).
Firefox ESR 52.9 is the last version for Windows XP.

I'm wondering if anyone has tried to install a later version (to get the
benefits of some code updates, particularly in regards to HTML5 video
playback capability). And if so, how far up in version numbers could you
go, before it refused to install or work?

(It looks like anything below version 62 is at least not "Quantum",
which is a plus, to me).
FF version 57 is the Quantum release, not version 62. v57 is when
XUL/XCOM legacy extensions got cut off and when Webextensions were
required.
Thanks for the correction on that. But my question was regarding
"installability", and if anyone had even tried to install and run an updated
version (updated beyond 52.9). I know it's not "supported", but that
doesn't mean you can't install it and run it. I figured somebody here might
have tried, and was curious as to their results.

The stub installer (aka web installer) you get from Mozilla will check
your OS to determine which is the latest version of Firefox it will
retrieve and install under your OS.

You can avoid the stub and get a file directly.
The EXE is an installer.

Firefox Setup 57.0.4.exe 34MB

If a person compiles the program from source, there
will be an opportunity to bypass the NSIS installer.
Or, find some article that mentions how to make
Firefox "portable", and bootstrap that way.

AFAIK, the NSIS installer is a Windows installer which
was available for free. Which is why they're using it
for the Windows builds.
