Yes, I had added xpra to $PATH:
[bmishkania@ussd-prd-rdln01 xpra-2.2.3]$ which xpra
~/bin/xpra-2.2.3/bin/xpra
I tried building without Xdummy and ended up with a different error. Here is
what I did:
rm -r ~/bin/xpra-2.2.3/
./setup.py --without-Xdummy install --home=/home/bmishkania/bin/xpra-2.2.3/
xpra start --start=~/bin/firefox/firefox --daemon=no
It prints this:
2018-01-24 20:03:58,708 cannot access python uinput module:
2018-01-24 20:03:58,708 No module named uinput

I do not think Xvfb is installed on this system, even though Xorg is. As an
unprivileged user it may be hard for me to install Xvfb, so could there be a
different solution?
Thanks,
Ben

This should not work unless you've also installed xpra somewhere on the
$PATH or modified $PATH.
You could also use the path to somewhere/install/bin/xpra directly.

Harmless warning, you don't have a system service, it will fallback to
self-daemonizing.

Harmless warning because you are missing the tmpfiles.d bits.

Harmless, you don't have uinput installed. You wouldn't be able to use
it anyway without the system service without also modifying the device
permissions.

Harmless, that's a known Xorg bug languishing upstream.

xpra_Xdummy failed to run, there could be a number of reasons for that.
The easiest fix for you might just be to switch to Xvfb:
./setup.py --without-Xdummy install --home=....
