User is running Ubuntu 16.04, kernel version 4.4.0-45-generic x86_64 , home is mounted on a separate partition, "Warning: cannot find home directory" and "Warning: cannot whitelist Downloads directory".

I also had this behavior and I think that is is because the separate home partition is not mounted properly (in a virtual machine with almost same setting but without separate home everything was fine).
And without a home directory at all something had to go wrong.

It also happens when you just execute firejail --overlay-tmpfs; then a firejailed shell appears but you can't do anything because there is no home directory.

With firejail --overlay-tmpfs --private firefox a firefox window appears but of course Downloads directory can't be whitelisted either and also --private option may be not wanted.
