AnduinOS is not Ubuntu. It is based on Ubuntu, but there are big differences, including differences in the way that you would install software packages. You'll be best advised to talk to people on the AnduinOS forum about difficulty installing various packages.

Execute the browsers from a terminal, look at the output there. What does it say?

You need to install missing packages.
It's better if you ask the AnduinOS community for help, since it's outside the browser's power.

libdbus is necessary for the browsers to properly integrate with the desktop on Linux (e.g. opening a new tab f it is already running and launching another instance from an external link).
If for some reason you can't install dbus on your system you could compile from source without dbus, but that will have some drawbacks for operation.

I think your getting that error because xulrunner package is not installed.
From a terminal run:
sudo apt-get update
After that completes
Run in terminal:
sudo apt-cache search xulrunner
Take note of the output and run from terminal:
sudo apt-get install xulrunner-29
if that is the version available for your distro.
You can install packages with Synaptic or Aptitude also if available.

It looks like you installed from the repo?
I find it easier to run palemoon from an extracted zip file, then all your dependencies are there

yes libdbus is not included in base install in recent Ubuntu.
I think that running
sudo apt install libdbus-glib-1-2
should fix it.
