==== Set up the MOZ_HOST_BIN environment variable ====
The MOZ_HOST_BIN variable will need to be set to the directory with XPCShell on your machine.
You can execute the following command in the terminal, or it can be saved into .bashrc / .bash_profile for convinence:
<pre>export MOZ_HOST_BIN=/ABSOLUTE/PATH/TO/FIREFOX/SOURCE/{objdir}/dist/bin</pre>
If you're having difficulty finding the absolute path of XPCShell's directory, simply locate XPCShell in your {objdir}/dist/bin and execute the command pwd .
Again, {objdir} is a placeholder.
