Waterfox running under Xvnc inside a Docker container, a demented tool
to solve a demented problem.

Occasionally one needs to run dangerous code in a web brower, eg, some
dodgy Java app which is the only available interface to some critical
resource.  Running this in one's normal web browser is a bad idea.

So what one really wants here is a burner web browser.  Here you go.

See `create.sh` and `run.sh` for ways one might use the image.

Something along the lines of the `run.sh` formulation might work well
as the command portion of a tunneling `ssh -L 5900:127.0.0.1:5900` command.

This version is based on Ubuntu rather than Debian, because I was
trying to get the icedtea-web Java Plugin stuff to work.  Didn't work,
but then I tried a recipe for getting Java SE instead of OpenJDK, and
that does seem to work.  Might work equally well on Debian.

Sadly, this approach requires one to download JRE directly from
Oracle, get an account, and check through a license agreement, so I
can't just give it away, you'll have to download the JRE yourself.

Even with this, Java still whines a lot when dealing with the kind of
crappy old IPMI consoles that require this insanity in the first
place.  Among other things, Java whines that the crappy Java app
supplied by IPMI isn't signed properly (true), and therefore refuses
to run it (why were we doing this again?).  Once one gets past that,
one has to argue with Waterfox a bit to get it to believe that you
want to use `javaws` as the launcher for `jnlp` files.

You can bypass the Java whining by prepopulating
`/root/.java/deployment/security/exception.sites` with a URL
whitelist.  The format appears to be one URL per line, no comments or
other formatting.  Example:

```
https://ipmi.foo.example.org
https://ipmi.bar.example.org
```

There's probably some way to preset Waterfox's MIME handler for `jnlp`
files to run `/usr/bin/javaws` but after working out all of the above
I lack the patience to dig further today.
