Titanium - Error Loading Browser - MOZILLA_HOME_FIVE not set

Titanium - Error Loading Browser - MOZILLA_HOME_FIVE not set

Firstly, I am running on Manjaro Linux.
I downloaded Titanium, unzipped it, then ran it. All fine. However, at
startup it is throwing a "Cannot find chromimum. See documentation for
possible workaround/fixes" error which is then followed by a
MOZILLA_FIVE_HOME not set error and lastly it suggests that I should
terminate the workbench due to a SWT Error.
I've tried the many suggestions I've found online including:
Installing xulrunner. Did not work.
Setting an env variable called MOZILLA_FIVE_HOME according to
(http://www.eclipse.org/swt/faq.php#browserlinuxrcp). However, I may have
messeg up following these instructions. If anyone would kindly explain
what step number 2 means with a little bit of extra detail, I would
seriously appreciate it.
I will post the full error I am getting below:
