===Getting Firejail to work with Palemoon===

If you have palemoon downloaded as a binary, and not installed (also applies to waterfox per this link:
it won't run. Firejail says:
Error: No suitable palemoon executable found

This isn't working because you may have downloaded Palemoon in the home folder, which firejail doesn't give access to, as well as because palemoon is not linked in /usr/bin/ or equivalent (for your dist).

Solution:
ln -s /home/user/palemoon/palemoon /usr/bin/palemoon
nano /etc/firejail/palemoon.profile
add the following
whitelist /home/user/palemoon/
