Did you install it SUID?

$ ls -l /usr/bin/firejail
-rwsr-xr-x 1 root root 1338184 Jun 24 11:50 /usr/bin/firejail

$ls -lh /usr/bin/firejail
-rwsr-xr-x 1 65534 65534 295K Jun 14 19:20 /usr/bin/firejail

Yup. (This is within the jail, hence the different UID and GID).

I think I wasn't clear - this is within the jail (not outside).

Not a problem, the jail actually will prevent a new jail for starting - firejail is a SUID executable, and SUID executables are disabled.

Huh...okay. I realized that, but it's interesting that it would have to set the UID and GID to root before it even did the argument parsing (which would tell it that it just has to display the version).
